How to Write an Abstract | Steps & Examples

Published on February 28, 2019 by Shona McCombes . Revised on July 18, 2023 by Eoghan Ryan.

How to Write an Abstract

An abstract is a short summary of a longer work (such as a thesis ,  dissertation or research paper ). The abstract concisely reports the aims and outcomes of your research, so that readers know exactly what your paper is about.

Although the structure may vary slightly depending on your discipline, your abstract should describe the purpose of your work, the methods you’ve used, and the conclusions you’ve drawn.

One common way to structure your abstract is to use the IMRaD structure. This stands for:

  • Introduction

Abstracts are usually around 100–300 words, but there’s often a strict word limit, so make sure to check the relevant requirements.

In a dissertation or thesis , include the abstract on a separate page, after the title page and acknowledgements but before the table of contents .

Hover over the different parts of the abstract to see how it is constructed.

This paper examines the role of silent movies as a mode of shared experience in the US during the early twentieth century. At this time, high immigration rates resulted in a significant percentage of non-English-speaking citizens. These immigrants faced numerous economic and social obstacles, including exclusion from public entertainment and modes of discourse (newspapers, theater, radio).

Incorporating evidence from reviews, personal correspondence, and diaries, this study demonstrates that silent films were an affordable and inclusive source of entertainment. It argues for the accessible economic and representational nature of early cinema. These concerns are particularly evident in the low price of admission and in the democratic nature of the actors’ exaggerated gestures, which allowed the plots and action to be easily grasped by a diverse audience despite language barriers.

Keywords: silent movies, immigration, public discourse, entertainment, early cinema, language barriers.

Discover proofreading & editing

You will almost always have to include an abstract when:

  • Completing a thesis or dissertation
  • Submitting a research paper to an academic journal
  • Writing a book or research proposal
  • Applying for research grants

It’s easiest to write your abstract last, right before the proofreading stage, because it’s a summary of the work you’ve already done. Your abstract should:

  • Be a self-contained text, not an excerpt from your paper
  • Be fully understandable on its own
  • Reflect the structure of your larger work

Start by clearly defining the purpose of your research. What practical or theoretical problem does the research respond to, or what research question did you aim to answer?

You can include some brief context on the social or academic relevance of your dissertation topic , but don’t go into detailed background information. If your abstract uses specialized terms that would be unfamiliar to the average academic reader or that have various different meanings, give a concise definition.

After identifying the problem, state the objective of your research. Use verbs like “investigate,” “test,” “analyze,” or “evaluate” to describe exactly what you set out to do.

This part of the abstract can be written in the present or past simple tense  but should never refer to the future, as the research is already complete.

  • This study will investigate the relationship between coffee consumption and productivity.
  • This study investigates the relationship between coffee consumption and productivity.

Next, indicate the research methods that you used to answer your question. This part should be a straightforward description of what you did in one or two sentences. It is usually written in the past simple tense, as it refers to completed actions.

  • Structured interviews will be conducted with 25 participants.
  • Structured interviews were conducted with 25 participants.

Don’t evaluate validity or obstacles here — the goal is not to give an account of the methodology’s strengths and weaknesses, but to give the reader a quick insight into the overall approach and procedures you used.

Next, summarize the main research results . This part of the abstract can be in the present or past simple tense.

  • Our analysis has shown a strong correlation between coffee consumption and productivity.
  • Our analysis shows a strong correlation between coffee consumption and productivity.
  • Our analysis showed a strong correlation between coffee consumption and productivity.

Depending on how long and complex your research is, you may not be able to include all results here. Try to highlight only the most important findings that will allow the reader to understand your conclusions.

Finally, you should discuss the main conclusions of your research : what is your answer to the problem or question? The reader should finish with a clear understanding of the central point that your research has proved or argued. Conclusions are usually written in the present simple tense.

  • We concluded that coffee consumption increases productivity.
  • We conclude that coffee consumption increases productivity.

If there are important limitations to your research (for example, related to your sample size or methods), you should mention them briefly in the abstract. This allows the reader to accurately assess the credibility and generalizability of your research.

If your aim was to solve a practical problem, your discussion might include recommendations for implementation. If relevant, you can briefly make suggestions for further research.

If your paper will be published, you might have to add a list of keywords at the end of the abstract. These keywords should reference the most important elements of the research to help potential readers find your paper during their own literature searches.

Be aware that some publication manuals, such as APA Style , have specific formatting requirements for these keywords.

It can be a real challenge to condense your whole work into just a couple of hundred words, but the abstract will be the first (and sometimes only) part that people read, so it’s important to get it right. These strategies can help you get started.

Read other abstracts

The best way to learn the conventions of writing an abstract in your discipline is to read other people’s. You probably already read lots of journal article abstracts while conducting your literature review —try using them as a framework for structure and style.

You can also find lots of dissertation abstract examples in thesis and dissertation databases .

Reverse outline

Not all abstracts will contain precisely the same elements. For longer works, you can write your abstract through a process of reverse outlining.

For each chapter or section, list keywords and draft one to two sentences that summarize the central point or argument. This will give you a framework of your abstract’s structure. Next, revise the sentences to make connections and show how the argument develops.

Write clearly and concisely

A good abstract is short but impactful, so make sure every word counts. Each sentence should clearly communicate one main point.

To keep your abstract or summary short and clear:

  • Avoid passive sentences: Passive constructions are often unnecessarily long. You can easily make them shorter and clearer by using the active voice.
  • Avoid long sentences: Substitute longer expressions for concise expressions or single words (e.g., “In order to” for “To”).
  • Avoid obscure jargon: The abstract should be understandable to readers who are not familiar with your topic.
  • Avoid repetition and filler words: Replace nouns with pronouns when possible and eliminate unnecessary words.
  • Avoid detailed descriptions: An abstract is not expected to provide detailed definitions, background information, or discussions of other scholars’ work. Instead, include this information in the body of your thesis or paper.

If you’re struggling to edit down to the required length, you can get help from expert editors with Scribbr’s professional proofreading services or use the paraphrasing tool .

Check your formatting

If you are writing a thesis or dissertation or submitting to a journal, there are often specific formatting requirements for the abstract—make sure to check the guidelines and format your work correctly. For APA research papers you can follow the APA abstract format .

Checklist: Abstract

The word count is within the required length, or a maximum of one page.

The abstract appears after the title page and acknowledgements and before the table of contents .

I have clearly stated my research problem and objectives.

I have briefly described my methodology .

I have summarized the most important results .

I have stated my main conclusions .

I have mentioned any important limitations and recommendations.

The abstract can be understood by someone without prior knowledge of the topic.

An abstract is a concise summary of an academic text (such as a journal article or dissertation ). It serves two main purposes:

  • To help potential readers determine the relevance of your paper for their own research.
  • To communicate your key findings to those who don’t have time to read the whole paper.

Abstracts are often indexed along with keywords on academic databases, so they make your work more easily findable. Since the abstract is the first thing any reader sees, it’s important that it clearly and accurately summarizes the contents of your paper.

An abstract for a thesis or dissertation is usually around 200–300 words. There’s often a strict word limit, so make sure to check your university’s requirements.

The abstract is the very last thing you write. You should only write it after your research is complete, so that you can accurately summarize the entirety of your thesis , dissertation or research paper .

Avoid citing sources in your abstract . There are two reasons for this:

  • The abstract should focus on your original research, not on the work of others.
  • The abstract should be self-contained and fully understandable without reference to other sources.

There are some circumstances where you might need to mention other sources in an abstract: for example, if your research responds directly to another study or focuses on the work of a single theorist. In general, though, don’t include citations unless absolutely necessary.

The abstract appears on its own page in the thesis or dissertation , after the title page and acknowledgements but before the table of contents .

What is an Abstract?

An abstract is a summary of a document, highlighting the full text's main ideas, key points, methodology, results, and conclusions. Its purpose is to quickly understand the document's content without reading the entire text. Abstracts are commonly used in academia and research to help readers assess the relevance and significance of a work.

What are the various structures of an Abstract?

Abstracts can have two main structures:

Structured Abstract:

It follows a specific format with sections like background/objective, methods, results, and conclusion.

Unstructured Abstract:

This format allows more flexibility and is often used in humanities and social sciences.

Both structures serve the purpose of providing a concise overview of the document's main content and findings.

What not to say in an abstract?

It is important to avoid providing excessive background information, detailed methodology, extensive citations, subjective statements, personal opinions, or ambiguous language in an abstract. The abstract should focus on conveying the key findings, main arguments, and implications of the research concisely and objectively.

What are the 4 C's of abstract writing?

The 4 C's of abstract writing are clarity, conciseness, completeness, and coherence. Clarity ensures that the abstract is easy to understand, conciseness involves presenting information succinctly, completeness includes covering all key aspects, and coherence ensures that the abstract flows logically and cohesively.

Why is writing an abstract so hard?

Writing an abstract can be challenging due to the inherent difficulty of condensing a complex and detailed content into a concise and coherent summary. It requires careful selection of information, balancing brevity with clarity, and effectively capturing the essence of the work while maintaining its relevance and significance.

What tense should be used in an abstract?

The present tense is commonly used in abstracts to describe the research findings, methodology, and conclusions. However, the specific tense usage may vary depending on the field or journal guidelines. It is recommended to consult the specific guidelines or conventions of the target publication for precise tense usage.

What is the first step in writing an abstract?

The first step in writing an abstract is thoroughly reading and understanding the entire document. Familiarize yourself with the research question, objectives, methodology, major findings, and conclusions. These steps help you identify the key elements that must be included in the abstract and ensure a comprehensive and accurate summary.

What are other tools by SpinBot?

The Dissertation Abstract: 101

How to write a clear & concise abstract (with examples).

By:   Madeline Fink (MSc) Reviewed By: Derek Jansen (MBA)   | June 2020

So, you’ve (finally) finished your thesis or dissertation or thesis. Now it’s time to write up your abstract (sometimes also called the executive summary). If you’re here, chances are you’re not quite sure what you need to cover in this section, or how to go about writing it. Fear not – we’ll explain it all in plain language , step by step , with clear examples .

Overview: The Dissertation/Thesis Abstract

  • What exactly is a dissertation (or thesis) abstract
  • What’s the purpose and function of the abstract
  • Why is the abstract so important
  • How to write a high-quality dissertation abstract
  • Example/sample of a quality abstract
  • Quick tips to write a high-quality dissertation abstract

What is an abstract?

Simply put, the abstract in a dissertation or thesis is a short (but well structured) summary that outlines the most important points of your research (i.e. the key takeaways). The abstract is usually 1 paragraph or about 300-500 words long (about one page), but but this can vary between universities.

A quick note regarding terminology – strictly speaking, an abstract and an executive summary are two different things when it comes to academic publications. Typically, an abstract only states what the research will be about, but doesn’t explore the findings – whereas an executive summary covers both . However, in the context of a dissertation or thesis, the abstract usually covers both, providing a summary of the full project.

In terms of content, a good dissertation abstract usually covers the following points:

  • The purpose of the research (what’s it about and why’s that important)
  • The methodology (how you carried out the research)
  • The key research findings (what answers you found)
  • The implications of these findings (what these answers mean)

We’ll explain each of these in more detail a little later in this post. Buckle up.

A good abstract should detail the purpose, the methodology, the key findings and the limitations of the research study.

What’s the purpose of the abstract?

A dissertation abstract has two main functions:

The first purpose is to  inform potential readers  of the main idea of your research without them having to read your entire piece of work. Specifically, it needs to communicate what your research is about (what were you trying to find out) and what your findings were . When readers are deciding whether to read your dissertation or thesis, the abstract is the first part they’ll consider. 

The second purpose of the abstract is to  inform search engines and dissertation databases  as they index your dissertation or thesis. The keywords and phrases in your abstract (as well as your keyword list) will often be used by these search engines to categorize your work and make it accessible to users. 

Simply put, your abstract is your shopfront display window – it’s what passers-by (both human and digital) will look at before deciding to step inside. 

The abstract serves to inform both potential readers (people) and search engine bots of the contents of your research.

Why’s it so important?

The short answer – because most people don’t have time to read your full dissertation or thesis! Time is money, after all…

If you think back to when you undertook your literature review , you’ll quickly realise just how important abstracts are! Researchers reviewing the literature on any given topic face a mountain of reading, so they need to optimise their approach. A good dissertation abstract gives the reader a “TLDR” version of your work – it helps them decide whether to continue to read it in its entirety. So, your abstract, as your shopfront display window, needs to “sell” your research to time-poor readers.

You might be thinking, “but I don’t plan to publish my dissertation”. Even so, you still need to provide an impactful abstract for your markers. Your ability to concisely summarise your work is one of the things they’re assessing, so it’s vital to invest time and effort into crafting an enticing shop window.  

A good abstract also has an added purpose for grad students . As a freshly minted graduate, your dissertation or thesis is often your most significant professional accomplishment and highlights where your unique expertise lies. Potential employers who want to know about this expertise are likely to only read the abstract (as opposed to reading your entire document) – so it needs to be good!

Think about it this way – if your thesis or dissertation were a book, then the abstract would be the blurb on the back cover. For better or worse, readers will absolutely judge your book by its cover .

Even if you have no intentions to publish  your work, you still need to provide an impactful abstract for your markers.

How to write your abstract

As we touched on earlier, your abstract should cover four important aspects of your research: the purpose , methodology , findings , and implications . Therefore, the structure of your dissertation or thesis abstract needs to reflect these four essentials, in the same order.  Let’s take a closer look at each of them, step by step:

Step 1: Describe the purpose and value of your research

Here you need to concisely explain the purpose and value of your research. In other words, you need to explain what your research set out to discover and why that’s important. When stating the purpose of research, you need to clearly discuss the following:

  • What were your research aims and research questions ?
  • Why were these aims and questions important?

It’s essential to make this section extremely clear, concise and convincing . As the opening section, this is where you’ll “hook” your reader (marker) in and get them interested in your project. If you don’t put in the effort here, you’ll likely lose their interest.

Step 2: Briefly outline your study’s methodology

In this part of your abstract, you need to very briefly explain how you went about answering your research questions . In other words, what research design and methodology you adopted in your research. Some important questions to address here include:

  • Did you take a qualitative or quantitative approach ?
  • Who/what did your sample consist of?
  • How did you collect your data?
  • How did you analyse your data?

Simply put, this section needs to address the “ how ” of your research. It doesn’t need to be lengthy (this is just a summary, after all), but it should clearly address the four questions above.

Step 3: Present your key findings

Next, you need to briefly highlight the key findings . Your research likely produced a wealth of data and findings, so there may be a temptation to ramble here. However, this section is just about the key findings – in other words, the answers to the original questions that you set out to address.

Again, brevity and clarity are important here. You need to concisely present the most important findings for your reader.

Step 4: Describe the implications of your research

Have you ever found yourself reading through a large report, struggling to figure out what all the findings mean in terms of the bigger picture? Well, that’s the purpose of the implications section – to highlight the “so what?” of your research. 

In this part of your abstract, you should address the following questions:

  • What is the impact of your research findings on the industry /field investigated? In other words, what’s the impact on the “real world”. 
  • What is the impact of your findings on the existing body of knowledge ? For example, do they support the existing research?
  • What might your findings mean for future research conducted on your topic?

If you include these four essential ingredients in your dissertation abstract, you’ll be on headed in a good direction.

The purpose of the implications section is to highlight the "so what?" of your research. In other words, to highlight its value.

Example: Dissertation/thesis abstract

Here is an example of an abstract from a master’s thesis, with the purpose , methods , findings , and implications colour coded.

The U.S. citizenship application process is a legal and symbolic journey shaped by many cultural processes. This research project aims to bring to light the experiences of immigrants and citizenship applicants living in Dallas, Texas, to promote a better understanding of Dallas’ increasingly diverse population. Additionally, the purpose of this project is to provide insights to a specific client, the office of Dallas Welcoming Communities and Immigrant Affairs, about Dallas’ lawful permanent residents who are eligible for citizenship and their reasons for pursuing citizenship status . The data for this project was collected through observation at various citizenship workshops and community events, as well as through semi-structured interviews with 14 U.S. citizenship applicants . Reasons for applying for U.S. citizenship discussed in this project include a desire for membership in U.S. society, access to better educational and economic opportunities, improved ease of travel and the desire to vote. Barriers to the citizenship process discussed in this project include the amount of time one must dedicate to the application, lack of clear knowledge about the process and the financial cost of the application. Other themes include the effects of capital on applicant’s experience with the citizenship process, symbolic meanings of citizenship, transnationalism and ideas of deserving and undeserving surrounding the issues of residency and U.S. citizenship. These findings indicate the need for educational resources and mentorship for Dallas-area residents applying for U.S. citizenship, as well as a need for local government programs that foster a sense of community among citizenship applicants and their neighbours.

Practical tips for writing your abstract

When crafting the abstract for your dissertation or thesis, the most powerful technique you can use is to try and put yourself in the shoes of a potential reader. Assume the reader is not an expert in the field, but is interested in the research area. In other words, write for the intelligent layman, not for the seasoned topic expert. 

Start by trying to answer the question “why should I read this dissertation?”

Remember the WWHS.

Make sure you include the  what , why ,  how , and  so what  of your research in your abstract:

  • What you studied (who and where are included in this part)
  • Why the topic was important
  • How you designed your study (i.e. your research methodology)
  • So what were the big findings and implications of your research

Keep it simple.

Use terminology appropriate to your field of study, but don’t overload your abstract with big words and jargon that cloud the meaning and make your writing difficult to digest. A good abstract should appeal to all levels of potential readers and should be a (relatively) easy read. Remember, you need to write for the intelligent layman.

Be specific.

When writing your abstract, clearly outline your most important findings and insights and don’t worry about “giving away” too much about your research – there’s no need to withhold information. This is the one way your abstract is not like a blurb on the back of a book – the reader should be able to clearly understand the key takeaways of your thesis or dissertation after reading the abstract. Of course, if they then want more detail, they need to step into the restaurant and try out the menu.

  • How to Write an Abstract for a Dissertation or Thesis
  • Doing a PhD

What is a Thesis or Dissertation Abstract?

The Cambridge English Dictionary defines an abstract in academic writing as being “ a few sentences that give the main ideas in an article or a scientific paper ” and the Collins English Dictionary says “ an abstract of an article, document, or speech is a short piece of writing that gives the main points of it ”.

Whether you’re writing up your Master’s dissertation or PhD thesis, the abstract will be a key element of this document that you’ll want to make sure you give proper attention to.

What is the Purpose of an Abstract?

The aim of a thesis abstract is to give the reader a broad overview of what your research project was about and what you found that was novel, before he or she decides to read the entire thesis. The reality here though is that very few people will read the entire thesis, and not because they’re necessarily disinterested but because practically it’s too large a document for most people to have the time to read. The exception to this is your PhD examiner, however know that even they may not read the entire length of the document.

Some people may still skip to and read specific sections throughout your thesis such as the methodology, but the fact is that the abstract will be all that most read and will therefore be the section they base their opinions about your research on. In short, make sure you write a good, well-structured abstract.

How Long Should an Abstract Be?

If you’re a PhD student, having written your 100,000-word thesis, the abstract will be the 300 word summary included at the start of the thesis that succinctly explains the motivation for your study (i.e. why this research was needed), the main work you did (i.e. the focus of each chapter), what you found (the results) and concluding with how your research study contributed to new knowledge within your field.

Woodrow Wilson, the 28th President of the United States of America, once famously said:

thesis abstracts online

The point here is that it’s easier to talk open-endedly about a subject that you know a lot about than it is to condense the key points into a 10-minute speech; the same applies for an abstract. Three hundred words is not a lot of words which makes it even more difficult to condense three (or more) years of research into a coherent, interesting story.

What Makes a Good PhD Thesis Abstract?

Whilst the abstract is one of the first sections in your PhD thesis, practically it’s probably the last aspect that you’ll ending up writing before sending the document to print. The reason being that you can’t write a summary about what you did, what you found and what it means until you’ve done the work.

A good abstract is one that can clearly explain to the reader in 300 words:

  • What your research field actually is,
  • What the gap in knowledge was in your field,
  • The overarching aim and objectives of your PhD in response to these gaps,
  • What methods you employed to achieve these,
  • You key results and findings,
  • How your work has added to further knowledge in your field of study.

Another way to think of this structure is:

  • Introduction,
  • Aims and objectives,
  • Discussion,
  • Conclusion.

Following this ‘formulaic’ approach to writing the abstract should hopefully make it a little easier to write but you can already see here that there’s a lot of information to convey in a very limited number of words.

How Do You Write a Good PhD Thesis Abstract?

The biggest challenge you’ll have is getting all the 6 points mentioned above across in your abstract within the limit of 300 words . Your particular university may give some leeway in going a few words over this but it’s good practice to keep within this; the art of succinctly getting your information across is an important skill for a researcher to have and one that you’ll be called on to use regularly as you write papers for peer review.

Keep It Concise

Every word in the abstract is important so make sure you focus on only the key elements of your research and the main outcomes and significance of your project that you want the reader to know about. You may have come across incidental findings during your research which could be interesting to discuss but this should not happen in the abstract as you simply don’t have enough words. Furthermore, make sure everything you talk about in your thesis is actually described in the main thesis.

Make a Unique Point Each Sentence

Keep the sentences short and to the point. Each sentence should give the reader new, useful information about your research so there’s no need to write out your project title again. Give yourself one or two sentences to introduce your subject area and set the context for your project. Then another sentence or two to explain the gap in the knowledge; there’s no need or expectation for you to include references in the abstract.

Explain Your Research

Some people prefer to write their overarching aim whilst others set out their research questions as they correspond to the structure of their thesis chapters; the approach you use is up to you, as long as the reader can understand what your dissertation or thesis had set out to achieve. Knowing this will help the reader better understand if your results help to answer the research questions or if further work is needed.

Keep It Factual

Keep the content of the abstract factual; that is to say that you should avoid bringing too much or any opinion into it, which inevitably can make the writing seem vague in the points you’re trying to get across and even lacking in structure.

Write, Edit and Then Rewrite

Spend suitable time editing your text, and if necessary, completely re-writing it. Show the abstract to others and ask them to explain what they understand about your research – are they able to explain back to you each of the 6 structure points, including why your project was needed, the research questions and results, and the impact it had on your research field? It’s important that you’re able to convey what new knowledge you contributed to your field but be mindful when writing your abstract that you don’t inadvertently overstate the conclusions, impact and significance of your work.

Thesis and Dissertation Abstract Examples

Perhaps the best way to understand how to write a thesis abstract is to look at examples of what makes a good and bad abstract.

Example of A Bad Abstract

Let’s start with an example of a bad thesis abstract:

In this project on “The Analysis of the Structural Integrity of 3D Printed Polymers for use in Aircraft”, my research looked at how 3D printing of materials can help the aviation industry in the manufacture of planes. Plane parts can be made at a lower cost using 3D printing and made lighter than traditional components. This project investigated the structural integrity of EBM manufactured components, which could revolutionise the aviation industry.

What Makes This a Bad Abstract

Hopefully you’ll have spotted some of the reasons this would be considered a poor abstract, not least because the author used up valuable words by repeating the lengthy title of the project in the abstract.

Working through our checklist of the 6 key points you want to convey to the reader:

  • There has been an attempt to introduce the research area , albeit half-way through the abstract but it’s not clear if this is a materials science project about 3D printing or is it about aircraft design.
  • There’s no explanation about where the gap in the knowledge is that this project attempted to address.
  • We can see that this project was focussed on the topic of structural integrity of materials in aircraft but the actual research aims or objectives haven’t been defined.
  • There’s no mention at all of what the author actually did to investigate structural integrity. For example was this an experimental study involving real aircraft, or something in the lab, computer simulations etc.
  • The author also doesn’t tell us a single result of his research, let alone the key findings !
  • There’s a bold claim in the last sentence of the abstract that this project could revolutionise the aviation industry, and this may well be the case, but based on the abstract alone there is no evidence to support this as it’s not even clear what the author did .

This is an extreme example but is a good way to illustrate just how unhelpful a poorly written abstract can be. At only 71 words long, it definitely hasn’t maximised the amount of information that could be presented and the what they have presented has lacked clarity and structure.

A final point to note is the use of the EBM acronym, which stands for Electron Beam Melting in the context of 3D printing; this is a niche acronym for the author to assume that the reader would know the meaning of. It’s best to avoid acronyms in your abstract all together even if it’s something that you might expect most people to know about, unless you specifically define the meaning first.

Example of A Good Abstract

Having seen an example of a bad thesis abstract, now lets look at an example of a good PhD thesis abstract written about the same (fictional) project:

Additive manufacturing (AM) of titanium alloys has the potential to enable cheaper and lighter components to be produced with customised designs for use in aircraft engines. Whilst the proof-of-concept of these have been promising, the structural integrity of AM engine parts in response to full thrust and temperature variations is not clear.

The primary aim of this project was to determine the fracture modes and mechanisms of AM components designed for use in Boeing 747 engines. To achieve this an explicit finite element (FE) model was developed to simulate the environment and parameters that the engine is exposed to during flight. The FE model was validated using experimental data replicating the environmental parameters in a laboratory setting using ten AM engine components provided by the industry sponsor. The validated FE model was then used to investigate the extent of crack initiation and propagation as the environment parameters were adjusted.

This project was the first to investigate fracture patterns in AM titanium components used in aircraft engines; the key finding was that the presence of cavities within the structures due to errors in the printing process, significantly increased the risk of fracture. Secondly, the simulations showed that cracks formed within AM parts were more likely to worsen and lead to component failure at subzero temperatures when compared to conventionally manufactured parts. This has demonstrated an important safety concern which needs to be addressed before AM parts can be used in commercial aircraft.

What Makes This a Good Abstract

Having read this ‘good abstract’ you should have a much better understand about what the subject area is about, where the gap in the knowledge was, the aim of the project, the methods that were used, key results and finally the significance of these results. To break these points down further, from this good abstract we now know that:

  • The research area is around additive manufacturing (i.e. 3D printing) of materials for use in aircraft.
  • The gap in knowledge was how these materials will behave structural when used in aircraft engines.
  • The aim was specifically to investigate how the components can fracture.
  • The methods used to investigate this were a combination of computational and lab based experimental modelling.
  • The key findings were the increased risk of fracture of these components due to the way they are manufactured.
  • The significance of these findings were that it showed a potential risk of component failure that could comprise the safety of passengers and crew on the aircraft.

The abstract text has a much clearer flow through these different points in how it’s written and has made much better use of the available word count. Acronyms have even been used twice in this good abstract but they were clearly defined the first time they were introduced in the text so that there was no confusion about their meaning.

The abstract you write for your dissertation or thesis should succinctly explain to the reader why the work of your research was needed, what you did, what you found and what it means. Most people that come across your thesis, including any future employers, are likely to read only your abstract. Even just for this reason alone, it’s so important that you write the best abstract you can; this will not only convey your research effectively but also put you in the best light possible as a researcher.

The abstract provides a brief overview of the research assignment. So, this part gives a general assessment of the work and encourages the reader to explore it further. Almost every student dealt with the difficult task of condensing their research results into several hundred words. But that’s not a problem anymore!

We used artificial intelligence to make a tool that will make your academic life more enjoyable . You can get an excellent example of an abstract specifically for your research paper in minutes. To do this, you need to specify the reason for the research, the problems, and the goals. Also, we recommend mentioning the methodology and your findings to ensure the outcome is accurate. After that, the AI abstract maker will do the rest for you!

Key Reasons to Use Our Online Abstract Generator

Students juggle various assignments and obligations. Research papers are among the most challenging tasks they have to complete. What makes them so difficult is the sheer volume of information and study involved. Dealing with large amounts of material often leaves students drained and incapable of summarizing their work correctly.

Our abstract generator for research papers makes this process more straightforward thanks to several factors:

✅ Customization The platform generates abstracts for all types of papers.
✅ Free use Our tool is provided completely free of charge.
✅ Speed The abstract generator produces results in a matter of minutes.
✅ User-friendliness The summary AI writer is accessible to people from all walks of life.

Abstracts provide short summaries of larger works, including research papers and dissertations. Readers scan them to decide whether or not they wish to continue reading the rest of the paper. In about 150–200 words, you should state the problem and provide the research goal, results, implications, and used methods.

One should write research abstracts only after the rest of the work is ironed out and ready. While this part of research may seem insignificant, students should take the time to write the abstract well. Doing so lets them identify any flaws in the research methodology and results.

Types of Research Paper Abstracts

Many students believe that abstracts come only in one type. In reality, there are several versions of summaries used in academic circles.

  • Critical Abstract . These are the most extensive abstracts, at around 450 words. Unlike other entries on this list, they encourage deep analysis: for example, a discussion about the validity or reliability of their studies. It’s mostly used in social science research .
  • Descriptive Abstract . This format is quite similar to informative abstracts but much shorter. On average, this type is only 100 words long and covers the main focus of the studies. Descriptive summaries offer no conclusions or recommendations for further research.
  • Highlight Abstract . Students rarely get to use this type, as its primary goal is to get the reader’s attention. Highlight abstracts don’t helpfully summarize papers . Instead, they concentrate on the unique parts of the research, such as its results and conclusions.
  • Informative Abstract . This is the most common type used by researchers and writers. It provides primary information about research concepts, methodology, findings, and recommendations. Sometimes, informative research abstracts have keywords listed at the bottom, but this practice is mainly reserved for professional publications.

✍️ How to Write an Abstract in 5 Steps

Despite the incredible versatility of our abstract generator, it’s still important to learn how to make abstracts on your own. We’ve dedicated this part of the guide to the five steps of writing these summaries. So, these instructions will help you create an abstract for any academic paper.

  • Write the paper . To create an abstract, you first need a research paper. Create an outline of the study detailing the problem and methods you’ll use to address it. Explain the research methodology, state what information can be extracted from it, and show how the findings apply to the overall field of study.
  • Review paper requirements . Once you’re done with the draft, review the criteria provided by the educational institution. Use the supporting documents with instructions, as they can clarify the requirements for the work's style, formatting, and length. Different disciplines require specific styles, so read this information carefully.
  • Consider the audience . When working on an abstract, it’s crucial to identify who will be reading it afterward. For example, students often adjust their language to reach the general public and not only their respective professors.
  • Write the abstract . Now, write the abstract based on the provided requirements. Use the body of the research to summarize the problem, explain the methods used in the paper , and show what their results were. Finish the summary by telling why your findings are valuable to the study field and what can be done in further research.
  • Iron it out . Like with all writing pieces, it's essential to review the abstract and check if it has all the necessary components. The text should be easy to follow, cover all points, and be informative. As the abstract creates the first impression, make it a good one.

Abstract Formats: MLA & APA Styles

Abstract types aren’t the only things students should look out for. In academic settings, several formatting styles detail how the text should look on paper. The majority of US colleges use two popular methods: MLA and APA . Here, we discuss how abstracts look in each of them.

  • Abstracts have their own page directly after the title or cover pages.
  • In the APA style, the first line on the page is the word “Abstract” in the center without quotation marks.
  • The following line in APA abstracts summarizes the critical points of the research. It introduces the main topic, questions, methodology, findings, and conclusions.
  • Use double spaces and make the abstract under 250 words.
  • Include keywords after the summary in APA format to help people find the work in various databases.
  • Start with a sentence that contains the thesis statement and reason for readers to care about the research.
  • Use short and simple sentences with precise words and phrases, as the abstract needs to be easy-to-understand.
  • Use transitional words and phrases to make the writing flow and connect ideas more efficiently.
  • Edit the abstract until it is 5-7 sentences long or under 250 words.
  • Avoid using footnotes and citations.

🫣 7 Mistakes You Should Avoid When Writing an Abstract

Writing abstracts is a pretty straightforward process. But it doesn’t mean that everybody is immune from making mistakes, especially after spending days toiling away on a research paper.

There are seven common errors everybody should check before submitting an abstract.

  • Making it too long . A summary should concisely describe the whole paper. Avoid repetition and details that have little to do with the research.
  • Using chopped-up sentences . Ensure that your paper contains only complete sentences. It makes the work more professional and easier to comprehend.
  • Adding too much technical jargon . Keep things simple so that anyone reading the abstract understands what it’s about. It will also make more people check out your paper.
  • Not correcting the text . Sometimes, students want to finish a work without editing it too much. Take the time and comb the document for errors and factual mistakes.
  • Failing to explain the significance of the research . The first couple of sentences should give readers a clear understanding of why the study is essential.
  • Using the wrong tense . It’s recommended that abstracts be written in the past tense. Some academic institutions won’t accept papers with improperly written abstracts.
  • Too many adjectives and hyperboles . You aren’t writing a 19th-century novel but an academic paper. The work should reflect that, so avoid using too many literary devices .

What Is a Dissertation Abstract?

Dissertation abstracts, by definition, are summaries of a thesis's content, usually between 200 and 300 words, used to inform readers about the contents of the study in a quick way. A thesis or dissertation abstract briefly overviews the entire thesis. Dissertation abstracts are found at the beginning of every study, providing the research recap, results, and conclusions. It usually goes right after your title page and before your dissertation table of contents . An abstract for a dissertation (alternatively called “précis” further in the article) should clearly state the main topic of your paper, its overall purpose, and any important research questions or findings. It should also contain any necessary keywords that direct readers to relevant information. In addition, it addresses any implications for further research that may stem from its field. Writing strong précis requires you to think carefully, as they are the critical components that attract readers to peruse your paper.

Dissertation Abstract

Purpose of a Dissertation or Thesis Abstract

The primary purpose of an abstract in a dissertation or thesis is to give readers a basic understanding of the completed work. Also, it should create an interest in the topic to motivate readers to read further. Writing an abstract for a dissertation is essential for many reasons: 

  • Offers a summary and gives readers an overview of what they should expect from your study.
  • Provides an opportunity to showcase the research done, highlighting its importance and impact.
  • Identifies any unexplored research gaps to inform future studies and direct the current state of knowledge on the topic.

In general, an abstract of a thesis or a dissertation is a bridge between the research and potential readers.

What Makes a Good Abstract for a Dissertation?

Making a good dissertation abstract requires excellent organization and clarity of thought. Proper specimens must provide convincing arguments supporting your thesis. Writing an effective dissertation abstract requires students to be concise and write engagingly. Below is a list of things that makes it outstanding:

  • Maintains clear and concise summary style
  • Includes essential keywords for search engine optimization
  • Accurately conveys the scope of the thesis
  • Strictly adheres to the word count limit specified in your instructions
  • Written from a third-person point of view
  • Includes objectives, approach, and findings
  • Uses simple language without jargon
  • Avoids overgeneralized statements or vague claims.

How Long Should a Dissertation Abstract Be?

Abstracts should be long enough to convey the key points of every thesis, yet brief enough to capture readers' attention. A dissertation abstract length should typically be between 200-300 words, i.e., 1 page. But usually, length is indicated in the requirements. Remember that your primary goal here is to provide an engaging and informative thesis summary. Note that following the instructions and templates set forth by your university will ensure your thesis or dissertation abstract meets the writing criteria and adheres to all relevant standards.

Dissertation Abstract Structure

Dissertation abstracts can be organized in different ways and vary slightly depending on your work requirements. However, each abstract of a dissertation should incorporate elements like keywords, methods, results, and conclusions. The structure of a thesis or a dissertation abstract should account for the components included below:

  • Title Accurately reflects the topic of your thesis.
  • Introduction Provides an overview of your research, its purpose, and any relevant background information.
  • Methods/ Approach Gives an outline of the methods used to conduct your research.
  • Results Summarizes your findings.
  • Conclusions Provides an overview of your research's accomplishments and implications.
  • Keywords Includes keywords that accurately describe your thesis.

Below is an example that shows how a dissertation abstract looks, how to structure it and where each part is located. Use this template to organize your own summary. 

Dissertation Abstract

Things to Consider Before Writing a Dissertation Abstract

There are several things you should do beforehand in order to write a good abstract for a dissertation or thesis. They include:

  • Reviewing set requirements and making sure you clearly understand the expectations
  • Reading other research works to get an idea of what to include in yours
  • Writing a few drafts before submitting your final version, which will ensure that it's in the best state possible.

Write an Abstract for a Dissertation Last

Remember, it's advisable to write an abstract for a thesis paper or dissertation last. Even though it’s always located in the beginning of the work, nevertheless, it should be written last. This way, your summary will be more accurate because the main argument and conclusions are already known when the work is mostly finished - it is incomparably easier to write a dissertation abstract after completing your thesis. Additionally, you should write it last because the contents and scope of the thesis may have changed during the writing process. So, create your dissertation abstract as a last step to help ensure that it precisely reflects the content of your project.

Carefully Read Requirements

Writing dissertation abstracts requires careful attention to details and adherence to writing requirements. Refer to the rubric or guidelines that you were presented with to identify aspects to keep in mind and important elements, such as correct length and writing style, and then make sure to comprehensively include them. Careful consideration of these requirements ensures that your writing meets every criterion and standard provided by your supervisor to increase the chances that your master's thesis is accepted and approved.   

Choose the Right Type of Dissertation Abstracts

Before starting to write a dissertation or thesis abstract you should choose the appropriate type. Several options are available, and it is essential to pick one that best suits your dissertation's subject. Depending on their purpose, there exist 3 types of dissertation abstracts: 

  • Informative
  • Descriptive

Informative one offers readers a concise overview of your research, its purpose, and any relevant background information. Additionally, this type includes brief summaries of all results and dissertation conclusions .  A descriptive abstract in a dissertation or thesis provides a quick overview of the research, but it doesn't incorporate any evaluation or analysis because it only offers a snapshot of the study and makes no claims.

Critical abstract gives readers an in-depth overview of the research and include an evaluative component. This means that this type also summarizes and analyzes research data, discusses implications, and makes claims about the achievements of your study. In addition, it examines the research data and recounts its implications. 

Choose the correct type of dissertation abstract to ensure that it meets your paper’s demands.

How to Write an Abstract for a Dissertation or Thesis?

Writing a good abstract for a dissertation or thesis is essential as it provides a brief overview of the completed research. So, how to write a dissertation abstract? First of all, the right approach is dictated by an institution's specific requirements. However, a basic structure should include the title, an introduction to your topic, research methodology, findings, and conclusions. Composing noteworthy precis allows you to flaunt your capabilities and grants readers a concise glimpse of the research. Doing this can make an immense impact on those reviewing your paper.

1. Identify the Purpose of Your Study

An abstract for thesis paper or dissertation is mainly dependent on the purpose of your study. Students need to identify all goals and objectives of their research before writing their précis - the reason being to ensure that the investigation’s progress and all its consequent findings are described simply and intelligibly. Additionally, one should provide some background information about their study. A short general description helps your reader acknowledge and connect with the research question. But don’t dive too deep into details, since more details are provided when writing a dissertation introduction . Scholars should write every dissertation abstract accurately and in a coherent way to demonstrate their knowledge and understanding of the area. This is the first section that potential readers will see, and it should serve as a precise overview of an entire document. Therefore, researchers writing abstracts of a thesis or dissertation should do it with great care and attention to details.

2. Discuss Methodology

A writer needs to elaborate on their methodological approach in an abstract of PhD dissertation since it acts as a brief summary of a whole research and should include an explanation of all methods used there. Dissertation and thesis abstracts discuss the research methodology by providing information sufficient enough to understand the underlying research question, data collection methods, and approach employed. Additionally, they should explain the analysis or interpretation of the data. This will help readers to gain a much better understanding of the research process and allow them to evaluate the data quality. Mention whether your methodology is quantitative or qualitative since this information is essential for readers to grasp your study's context and scope. Additionally, comment on the sources used and any other evidence collected. Furthermore, explain why you chose the method in the first place. All in all, addressing methodology is a crucial part of writing abstracts of a thesis or dissertation, as it will allow people to understand exactly how you arrived at your conclusions.

3. Describe the Key Results

Write your abstract for dissertation in a way that includes an overview of the research problem, your proposed solution, and any limitations or constraints you faced. Students need to briefly and clearly describe all key findings from the research. You must ensure that the results mentioned in an abstract of a thesis or dissertation are supported with evidence from body chapters.  Write about any crucial trends or patterns that emerged from the study. They should be discussed in detail, as this information can often provide valuable insight into your topic. Be sure to include any correlations or relationships found as a result of the study. Correlation, in this context, refers to any association between two or more variables.  Finally, write about any implications or conclusions drawn from your results: this is an essential element when writing an abstract for dissertation since it allows readers to firmly comprehend the study’s significance.

4. Summarize an Abstract for a Dissertation

Knowing how to write an abstract for dissertation is critical in conveying your work to a broad audience. Summarizing can be challenging (since precis is a summary in itself), but it is an essential part of any successful work. So, as a final step, conclude this section with a brief overview of the topic, outline the course of your research and its main results, and answer the paper’s central question.  Summarizing an abstract of your dissertation is done to give readers a succinct impression of the entire paper, making an accurate and concise overview of all its key points and consequent conclusions. In every PhD dissertation abstract , wrap up its summary by addressing any unanswered questions and discussing any potential implications of the research.

How to Format an Abstract in Dissertation

Format depends on the style (APA, MLA, Harvard, Chicago), which varies according to your subject's discipline. Style to use is usually mentioned in the instructions, and students should follow them closely to ensure formatting accuracy. These styles have guidelines that inform you about the formatting of titles, headings and subheadings, margins, page numbers, abstracts, and tell what font size and family or line spacing are required. Using a consistent formatting style ensures proper readability and might even influence paper’s overall structure. Another formatting concern to consider when writing dissertation and thesis abstracts is their layout. Most commonly, your paper should have a one-inch margin on all sides with double spacing. Be sure to familiarize yourself with the right guidelines to get the correct information on how to write dissertation abstract in APA format and ensure that it meets formatting standards.

Keywords in a Dissertation Abstract

When writing thesis abstracts, it is essential to include keywords. Keywords are phrases or words that help readers identify main topics of your paper and make it easier for them to find any information they need. Keywords should usually be placed at the end of a dissertation abstract and written in italics. In addition, include keywords that represent your paper's primary research interests and topics. Lastly, use keywords throughout your thesis to ensure that your prĂŠcis accurately reflect an entire paper's content.

🤔 Why Use Online Abstract Generator?

Having trouble writing an abstract? You’re not alone.

Crafting an abstract can be problematic, especially when dealing with voluminous work. After all, converting a 100-page academic paper into 150 words is not an easy task. And this is where an abstract maker can help you immensely.

The amount of time you’ll save by relying on a machine to do the work for you is huge. Not to mention the result will be entirely error-free. No logical, grammatical, or other mistakes will spoil your piece.

Sounds interesting? Then, keep reading to learn more about abstracts and our generator.

An abstract is a brief summary of a work. Usually, it's a single paragraph containing 150 to 250 words. It describes all the key points and elements of an article, essay, or work of any other format.

Keep in mind that an abstract merely describes a text. It shouldn’t be an evaluation or an attempt to defend the paper. Instead, it’s just an overview.

Structure of an Abstract

An abstract is not a simple summary. It has a specific structure and should contain the following elements:

  • The main issue . Describe the problem you are trying to solve with your research.
  • The background . Include everything the reader needs to know before delving into your text.
  • The goal . Don’t forget to describe the reasons behind your work.
  • The methods . Tell the readers how exactly you performed your research.
  • The results . What did you discover? If no particular result comes to mind, you can list your arguments here instead.
  • The implications . Show the reader how significant your work is.

Remember that an abstract is separate from the rest of the paper. For the reader to get the complete picture of your research, your abstract must include everything listed above.

✍️ How to Write an Abstract

It can be tempting to go and write an abstract right away. But make sure to finish the planning of your work first. You want to write your abstract about your piece's contents, not build the contents around your abstract.

To make the writing process easier, divide it into 5 manageable steps:

  • Check the requirements. First off, you need to know how much you are allowed to write. An average abstract is about 150-250 words long, but there is often a strict limit. Make sure to stay within it!
  • Establish the goal and the problems of the research. The reader needs to know what your paper will be about right from the get-go. That’s why you need to formulate your thesis and showcase it first.
  • Establish the methods. Tell the reader how you did your research. Don’t go in too deep: simply describe the methods without unnecessary details.
  • Describe the results. Write a couple of sentences about the outcome of your investigation.
  • Write a conclusion. Address the issue you established in the second step. You might also want to mention your work’s limitations regarding your research samples or methods. Try to give the reader a clear understanding of your goal and how you achieved it.

Want to make the process even easier? Use our abstract tool! Online generators like ours will help you craft an excellent paragraph in a matter of seconds.

Abstract Writing Tips

Finally, we want to help you make your abstract truly amazing. Check out our best tips below:

  • It's best to get to the point immediately and without adding any filler or unnecessary details.
  • The less specific your abstract is, the better.
  • Check out some examples before you start writing. Sometimes the best way to learn something is to watch how everyone else does it.
  • Avoid long sentences or bizarre vocabulary to make an abstract paragraph as concise as possible.
  • It’s a great idea to single out some keywords from your outline and put them into your abstract.
  • Don't forget about formatting. Any serious academic work has its requirements. Make sure you check them before writing your piece.

Following these simple tips will make you a master of abstract writing.

✨ Free Abstract Sample

As an example, check out this abstract of the article “Bioeffcacy of Mentha piperita essential oil against dengue fever mosquito” by Sarita Kumar:

The Mentha balsamea, or peppermint plant, is a result of cross-breeding between spearmint and water mint. These plants are most commonly used in the area of repelling insects. The following research revolves around peppermint oil insect repellent and its development. As a part of an experiment, we obtained 25 grams of fresh peppermint and, after grinding it, put it in a glass jar with olive oil. The jar was then left for two days in a warm temperate. Next, the oil was strained with a cheesecloth, gathered, and diluted at 70%. It then got separated into three different spray bottles. The test was to put the spray sample into a jar with mosquitoes and equate the result to the same test with a commercial repellant. Thus, we challenged the stereotype of synthetic repellents being more efficient than their analogs made from natural materials.

That will be the end of our guide on abstract writing. Thank you for reading, and make sure to try out our abstract writer tool to get the best results!

EBSCO Open Dissertations

EBSCO Open Dissertations makes electronic theses and dissertations (ETDs) more accessible to researchers worldwide. The free portal is designed to benefit universities and their students and make ETDs more discoverable. 

Increasing Discovery & Usage of ETD Research

With EBSCO Open Dissertations, institutions are offered an innovative approach to driving additional traffic to ETDs in institutional repositories. Our goal is to help make their students’ theses and dissertations as widely visible and cited as possible.

EBSCO Open Dissertations extends the work started in 2014, when EBSCO and the H.W. Wilson Foundation created American Doctoral Dissertations which contained indexing from the H.W. Wilson print publication, Doctoral Dissertations Accepted by American Universities, 1933-1955. In 2015, the H.W. Wilson Foundation agreed to support the expansion of the scope of the American Doctoral Dissertations database to include records for dissertations and theses from 1955 to the present.

How Does EBSCO Open Dissertations Work?

Libraries can add theses and dissertations to the database, making them freely available to researchers everywhere while increasing traffic to their institutional repository.  ETD metadata is harvested via OAI and integrated into EBSCO’s platform, where pointers send traffic to the institution's IR.

EBSCO integrates this data into their current subscriber environments and makes the data available on the open web via opendissertations.org .

What this handout is about

This handout provides definitions and examples of the two main types of abstracts: descriptive and informative. It also provides guidelines for constructing an abstract and general tips for you to keep in mind when drafting. Finally, it includes a few examples of abstracts broken down into their component parts.

What is an abstract?

An abstract is a self-contained, short, and powerful statement that describes a larger work. Components vary according to discipline. An abstract of a social science or scientific work may contain the scope, purpose, results, and contents of the work. An abstract of a humanities work may contain the thesis, background, and conclusion of the larger work. An abstract is not a review, nor does it evaluate the work being abstracted. While it contains key words found in the larger work, the abstract is an original document rather than an excerpted passage.

Why write an abstract?

You may write an abstract for various reasons. The two most important are selection and indexing. Abstracts allow readers who may be interested in a longer work to quickly decide whether it is worth their time to read it. Also, many online databases use abstracts to index larger works. Therefore, abstracts should contain keywords and phrases that allow for easy searching.

Say you are beginning a research project on how Brazilian newspapers helped Brazil’s ultra-liberal president Luiz IgnĂĄcio da Silva wrest power from the traditional, conservative power base. A good first place to start your research is to search Dissertation Abstracts International for all dissertations that deal with the interaction between newspapers and politics. “Newspapers and politics” returned 569 hits. A more selective search of “newspapers and Brazil” returned 22 hits. That is still a fair number of dissertations. Titles can sometimes help winnow the field, but many titles are not very descriptive. For example, one dissertation is titled “Rhetoric and Riot in Rio de Janeiro.” It is unclear from the title what this dissertation has to do with newspapers in Brazil. One option would be to download or order the entire dissertation on the chance that it might speak specifically to the topic. A better option is to read the abstract. In this case, the abstract reveals the main focus of the dissertation:

This dissertation examines the role of newspaper editors in the political turmoil and strife that characterized late First Empire Rio de Janeiro (1827-1831). Newspaper editors and their journals helped change the political culture of late First Empire Rio de Janeiro by involving the people in the discussion of state. This change in political culture is apparent in Emperor Pedro I’s gradual loss of control over the mechanisms of power. As the newspapers became more numerous and powerful, the Emperor lost his legitimacy in the eyes of the people. To explore the role of the newspapers in the political events of the late First Empire, this dissertation analyzes all available newspapers published in Rio de Janeiro from 1827 to 1831. Newspapers and their editors were leading forces in the effort to remove power from the hands of the ruling elite and place it under the control of the people. In the process, newspapers helped change how politics operated in the constitutional monarchy of Brazil.

From this abstract you now know that although the dissertation has nothing to do with modern Brazilian politics, it does cover the role of newspapers in changing traditional mechanisms of power. After reading the abstract, you can make an informed judgment about whether the dissertation would be worthwhile to read.

Besides selection, the other main purpose of the abstract is for indexing. Most article databases in the online catalog of the library enable you to search abstracts. This allows for quick retrieval by users and limits the extraneous items recalled by a “full-text” search. However, for an abstract to be useful in an online retrieval system, it must incorporate the key terms that a potential researcher would use to search. For example, if you search Dissertation Abstracts International using the keywords “France” “revolution” and “politics,” the search engine would search through all the abstracts in the database that included those three words. Without an abstract, the search engine would be forced to search titles, which, as we have seen, may not be fruitful, or else search the full text. It’s likely that a lot more than 60 dissertations have been written with those three words somewhere in the body of the entire work. By incorporating keywords into the abstract, the author emphasizes the central topics of the work and gives prospective readers enough information to make an informed judgment about the applicability of the work.

When do people write abstracts?

  • when submitting articles to journals, especially online journals
  • when applying for research grants
  • when writing a book proposal
  • when completing the Ph.D. dissertation or M.A. thesis
  • when writing a proposal for a conference paper
  • when writing a proposal for a book chapter

Most often, the author of the entire work (or prospective work) writes the abstract. However, there are professional abstracting services that hire writers to draft abstracts of other people’s work. In a work with multiple authors, the first author usually writes the abstract. Undergraduates are sometimes asked to draft abstracts of books/articles for classmates who have not read the larger work.

Types of abstracts

There are two types of abstracts: descriptive and informative. They have different aims, so as a consequence they have different components and styles. There is also a third type called critical, but it is rarely used. If you want to find out more about writing a critique or a review of a work, see the UNC Writing Center handout on writing a literature review . If you are unsure which type of abstract you should write, ask your instructor (if the abstract is for a class) or read other abstracts in your field or in the journal where you are submitting your article.

Descriptive abstracts

A descriptive abstract indicates the type of information found in the work. It makes no judgments about the work, nor does it provide results or conclusions of the research. It does incorporate key words found in the text and may include the purpose, methods, and scope of the research. Essentially, the descriptive abstract describes the work being abstracted. Some people consider it an outline of the work, rather than a summary. Descriptive abstracts are usually very short—100 words or less.

Informative abstracts

The majority of abstracts are informative. While they still do not critique or evaluate a work, they do more than describe it. A good informative abstract acts as a surrogate for the work itself. That is, the writer presents and explains all the main arguments and the important results and evidence in the complete article/paper/book. An informative abstract includes the information that can be found in a descriptive abstract (purpose, methods, scope) but also includes the results and conclusions of the research and the recommendations of the author. The length varies according to discipline, but an informative abstract is rarely more than 10% of the length of the entire work. In the case of a longer work, it may be much less.

Here are examples of a descriptive and an informative abstract of this handout on abstracts . Descriptive abstract:

The two most common abstract types—descriptive and informative—are described and examples of each are provided.

Informative abstract:

Abstracts present the essential elements of a longer work in a short and powerful statement. The purpose of an abstract is to provide prospective readers the opportunity to judge the relevance of the longer work to their projects. Abstracts also include the key terms found in the longer work and the purpose and methods of the research. Authors abstract various longer works, including book proposals, dissertations, and online journal articles. There are two main types of abstracts: descriptive and informative. A descriptive abstract briefly describes the longer work, while an informative abstract presents all the main arguments and important results. This handout provides examples of various types of abstracts and instructions on how to construct one.

Which type should I use?

Your best bet in this case is to ask your instructor or refer to the instructions provided by the publisher. You can also make a guess based on the length allowed; i.e., 100-120 words = descriptive; 250+ words = informative.

How do I write an abstract?

The format of your abstract will depend on the work being abstracted. An abstract of a scientific research paper will contain elements not found in an abstract of a literature article, and vice versa. However, all abstracts share several mandatory components, and there are also some optional parts that you can decide to include or not. When preparing to draft your abstract, keep the following key process elements in mind:

  • Reason for writing: What is the importance of the research? Why would a reader be interested in the larger work?
  • Problem: What problem does this work attempt to solve? What is the scope of the project? What is the main argument/thesis/claim?
  • Methodology: An abstract of a scientific work may include specific models or approaches used in the larger study. Other abstracts may describe the types of evidence used in the research.
  • Results: Again, an abstract of a scientific work may include specific data that indicates the results of the project. Other abstracts may discuss the findings in a more general way.
  • Implications: What changes should be implemented as a result of the findings of the work? How does this work add to the body of knowledge on the topic?

(This list of elements is adapted with permission from Philip Koopman, “How to Write an Abstract.” )

All abstracts include:

  • A full citation of the source, preceding the abstract.
  • The most important information first.
  • The same type and style of language found in the original, including technical language.
  • Key words and phrases that quickly identify the content and focus of the work.
  • Clear, concise, and powerful language.

Abstracts may include:

  • The thesis of the work, usually in the first sentence.
  • Background information that places the work in the larger body of literature.
  • The same chronological structure as the original work.

How not to write an abstract:

  • Do not refer extensively to other works.
  • Do not add information not contained in the original work.
  • Do not define terms.

If you are abstracting your own writing

When abstracting your own work, it may be difficult to condense a piece of writing that you have agonized over for weeks (or months, or even years) into a 250-word statement. There are some tricks that you could use to make it easier, however.

Reverse outlining:

This technique is commonly used when you are having trouble organizing your own writing. The process involves writing down the main idea of each paragraph on a separate piece of paper– see our short video . For the purposes of writing an abstract, try grouping the main ideas of each section of the paper into a single sentence. Practice grouping ideas using webbing or color coding .

For a scientific paper, you may have sections titled Purpose, Methods, Results, and Discussion. Each one of these sections will be longer than one paragraph, but each is grouped around a central idea. Use reverse outlining to discover the central idea in each section and then distill these ideas into one statement.

Cut and paste:

To create a first draft of an abstract of your own work, you can read through the entire paper and cut and paste sentences that capture key passages. This technique is useful for social science research with findings that cannot be encapsulated by neat numbers or concrete results. A well-written humanities draft will have a clear and direct thesis statement and informative topic sentences for paragraphs or sections. Isolate these sentences in a separate document and work on revising them into a unified paragraph.

If you are abstracting someone else’s writing

When abstracting something you have not written, you cannot summarize key ideas just by cutting and pasting. Instead, you must determine what a prospective reader would want to know about the work. There are a few techniques that will help you in this process:

Identify key terms:

Search through the entire document for key terms that identify the purpose, scope, and methods of the work. Pay close attention to the Introduction (or Purpose) and the Conclusion (or Discussion). These sections should contain all the main ideas and key terms in the paper. When writing the abstract, be sure to incorporate the key terms.

Highlight key phrases and sentences:

Instead of cutting and pasting the actual words, try highlighting sentences or phrases that appear to be central to the work. Then, in a separate document, rewrite the sentences and phrases in your own words.

Don’t look back:

After reading the entire work, put it aside and write a paragraph about the work without referring to it. In the first draft, you may not remember all the key terms or the results, but you will remember what the main point of the work was. Remember not to include any information you did not get from the work being abstracted.

Revise, revise, revise

No matter what type of abstract you are writing, or whether you are abstracting your own work or someone else’s, the most important step in writing an abstract is to revise early and often. When revising, delete all extraneous words and incorporate meaningful and powerful words. The idea is to be as clear and complete as possible in the shortest possible amount of space. The Word Count feature of Microsoft Word can help you keep track of how long your abstract is and help you hit your target length.

Example 1: Humanities abstract

Kenneth Tait Andrews, “‘Freedom is a constant struggle’: The dynamics and consequences of the Mississippi Civil Rights Movement, 1960-1984” Ph.D. State University of New York at Stony Brook, 1997 DAI-A 59/02, p. 620, Aug 1998

This dissertation examines the impacts of social movements through a multi-layered study of the Mississippi Civil Rights Movement from its peak in the early 1960s through the early 1980s. By examining this historically important case, I clarify the process by which movements transform social structures and the constraints movements face when they try to do so. The time period studied includes the expansion of voting rights and gains in black political power, the desegregation of public schools and the emergence of white-flight academies, and the rise and fall of federal anti-poverty programs. I use two major research strategies: (1) a quantitative analysis of county-level data and (2) three case studies. Data have been collected from archives, interviews, newspapers, and published reports. This dissertation challenges the argument that movements are inconsequential. Some view federal agencies, courts, political parties, or economic elites as the agents driving institutional change, but typically these groups acted in response to the leverage brought to bear by the civil rights movement. The Mississippi movement attempted to forge independent structures for sustaining challenges to local inequities and injustices. By propelling change in an array of local institutions, movement infrastructures had an enduring legacy in Mississippi.

Now let’s break down this abstract into its component parts to see how the author has distilled his entire dissertation into a ~200 word abstract.

Example 2: Science Abstract

Luis Lehner, “Gravitational radiation from black hole spacetimes” Ph.D. University of Pittsburgh, 1998 DAI-B 59/06, p. 2797, Dec 1998

The problem of detecting gravitational radiation is receiving considerable attention with the construction of new detectors in the United States, Europe, and Japan. The theoretical modeling of the wave forms that would be produced in particular systems will expedite the search for and analysis of detected signals. The characteristic formulation of GR is implemented to obtain an algorithm capable of evolving black holes in 3D asymptotically flat spacetimes. Using compactification techniques, future null infinity is included in the evolved region, which enables the unambiguous calculation of the radiation produced by some compact source. A module to calculate the waveforms is constructed and included in the evolution algorithm. This code is shown to be second-order convergent and to handle highly non-linear spacetimes. In particular, we have shown that the code can handle spacetimes whose radiation is equivalent to a galaxy converting its whole mass into gravitational radiation in one second. We further use the characteristic formulation to treat the region close to the singularity in black hole spacetimes. The code carefully excises a region surrounding the singularity and accurately evolves generic black hole spacetimes with apparently unlimited stability.

This science abstract covers much of the same ground as the humanities one, but it asks slightly different questions.

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

Copyright ©1995-2018 by The Writing Lab & The OWL at Purdue and Purdue University. All rights reserved. This material may not be published, reproduced, broadcast, rewritten, or redistributed without permission. Use of this site constitutes acceptance of our terms and conditions of fair use.

Scholars often write abstracts for various applications: conference presentations may require an abstract or other short summary for a program; journal articles almost always require abstracts; invited talks and lectures are often advertised using an abstract. While the application may necessarily change the length of the abstract (a conference program may only allow for 50-75 words, for instance), the purpose and structure remains fairly constant.

Abstracts are generally kept brief (approximately 150-200 words). They differ by field, but in general, they need to summarize the article so that readers can decide if it is relevant to their work. The typical abstract includes these elements:

  • A statement of the problem and objectives
  • A statement of the significance of the work
  • A summary of employed methods or your research approach
  • A summary of findings or conclusions of the study
  • A description of the implications of the findings

Regardless of field, abstract authors should explain the purpose of the work, methods used, the results and the conclusions that can be drawn. However, each field purports slightly different ways to structure the abstract. A reliable strategy is to write the abstract as a condensed version of your article, with 1-2 sentences summarizing each major section. This means that in many of the sciences and a large portion of the humanities, abstracts follow a version of the IMRAD structure: Introduction, Methods, Results, and Discussion.

Most scientific journals require authors to submit such abstracts. It is generally advisable to write the abstract in the English language. That is because most papers in other languages, especially Asian nations, tend to publish an English abstract with common search engines, such as, the MLA site.

Example Abstract

This example abstract follows the IMRAD structure closely. The first two sentences are the introduction and background information. Sentences 3-5 describe the methods used in the study. Sentence 6 summarizes the results, while the last two sentences summarize the discussion and conclusion of the study; they also indicate the significance of the results.

Usability and User-Centered Theory for 21 st Century OWLs — by Dana Lynn Driscoll, H. Allen Brizee, Michael Salvo, and Morgan Sousa from The Handbook of Research on Virtual Workplaces and the New Nature of Business Practices . Eds. Kirk St. Amant and Pavel Zemlansky. Hershey, PA: Idea Group Publishing, 2008.

This article describes results of usability research conducted on the Purdue Online Writing Lab (OWL). The Purdue OWL is an information-rich educational website that provides free writing resources to users worldwide. Researchers conducted two generations of usability tests. In the first test, participants were asked to navigate the OWL and answer questions. Results of the first test and user-centered scholarship indicated that a more user-centered focus would improve usability. The second test asked participants to answer writing-related questions using both the OWL website and a user-centered OWL prototype. Participants took significantly less time to find information using the prototype and reported a more positive response to the user-centered prototype than the original OWL. Researchers conclude that a user-centered website is more effective and can be a model for information-rich online resources. Researchers also conclude that usability research can be a productive source of ideas, underscoring the need for participatory invention.
