Essay Conclusions On Literature

What is a literature review?

A literature review is a critical analysis of published sources, or literature, on a particular topic. It is an assessment of the literature and provides a summary, classification, comparison and evaluation. At postgraduate level literature reviews can be incorporated into an article, a research report or thesis. At undergraduate level literature reviews can be a separate stand alone assessment.

The literature review is generally in the format of a standard essay made up of three components: an introduction, a body and a conclusion. It is not a list like an annotated bibliography in which a summary of each source is listed one by one.

Why do we write literature reviews?

At university you may be asked to write a literature review in order to demonstrate your understanding of the literature on a particular topic. You show your understanding by analysing and then synthesising the information to:

  • Determine what has already been written on a topic
  • Provide an overview of key concepts
  • Identify major relationships or patterns
  • Identify strengths and weaknesses
  • Identify any gaps in the research
  • Identify any conflicting evidence
  • Provide a solid background to a research paper’s investigation

How to write a literature review

Determine your purpose

Work out what you need to address in the literature review. What are you being asked to do in your literature review? What are you searching the literature to discover? Check your assignment question and your criteria sheet to know what to focus on.

Do an extensive search of the literature

Find out what has been written on the topic.

What kind of literature?

Select appropriate source material: Use a variety of academic or scholarly sources that are relevant, current and authoritative. An extensive review of relevant material will include — books, journal articles, reports, government documents, conference proceedings and web resources. The Library would be the best place to search for your sources.

How many resources?

The number of sources that you will be required to review will depend on what the literature review is for and how advanced you are in your studies. It could be from five sources at first year undergraduate level to more than fifty for a thesis. Your lecturer will advise you on these details.

Note the bibliographical details of your sources

Keep a note of the publication title, date, authors’ names, page numbers and publishers. These details will save you time later.

Read the literature

  • Critically read each source, look for the arguments presented rather than for facts.
  • Take notes as you read and start to organise your review around themes and ideas.
  • Consider using a table, matrix or concept map to identify how the different sources relate to each other.

Analyse the literature you have found

In order for your writing to reflect strong critical analysis, you need to evaluate the sources. For each source you are reviewing ask yourself these questions:

  • What are the key terms and concepts?
  • How relevant is this article to my specific topic?
  • What are the major relationships, trends and patterns?
  • How has the author structured the arguments?
  • How authoritative and credible is this source?
  • What are the differences and similarities between the sources?
  • Are there any gaps in the literature that require further study?

Write the review

  • Start by writing your thesis statement. This is an important introductory sentence that will tell your reader what the topic is and the overall perspective or argument you will be presenting.
  • Like essays, a literature review must have an introduction, a body and a conclusion.

Structure of a literature review


Your introduction should give an outline of

  • why you are writing a review, and why the topic is important
  • the scope of the review — what aspects of the topic will be discussed
  • the criteria used for your literature selection (e.g.. type of sources used, date range)
  • the organisational pattern of the review.

Body paragraphs

Each body paragraph should deal with a different theme that is relevant to your topic. You will need to synthesise several of your reviewed readings into each paragraph, so that there is a clear connection between the various sources. You will need to critically analyse each source for how they contribute to the themes you are researching.

The body could include paragraphs on:

  • historical background
  • methodologies
  • previous studies on the topic
  • mainstream versus alternative viewpoints
  • principal questions being asked
  • general conclusions that are being drawn.


Your conclusion should give a summary of:

  • the main agreements and disagreements in the literature
  • any gaps or areas for further research
  • your overall perspective on the topic.

Checklist for a literature review

Have I:

  • outlined the purpose and scope?
  • identified appropriate and credible (academic/scholarly) literature?
  • recorded the bibliographical details of the sources?
  • analysed and critiqued your readings?
  • identified gaps in the literature and research?
  • explored methodologies / theories / hypotheses / models?
  • discussed the varying viewpoints?
  • written an introduction, body and conclusion?
  • checked punctuation and spelling?

Further information

Okay, so you have written your initial draft. You have dotted all of the I’s and crossed all of the T’s. You know you have written the kind of essay that will blow the competition out of the water. However, as you will be aware the conclusion and the manner in which you bring a sense of closure to your critique is pivotal. Gloss over it and all of the time that you have invested in your essay to date will have been in vein. Go into overkill and you will be, well, killing the essay.

Before you start panicking or reaching for the delete button don’t worry, I you follow these basic rules then you won’t go far wrong:

  • Spend time on it
  • I have lost count of the times when I have been excitedly reading some brilliant essays only for them to fall flat at the final hurdle. Frankly, it defies logic that someone would invest so much time and effort into the introduction and main body, only to skip over the conclusion as though it were irrelevant. Tiredness or a desire to finish are not excuses. You have to polish, and re-polish until it is absolutely flawless.

  • Recap on the central argument of your argument
  • There is an art to doing this, and once you have written several essays, you will find yourself getting into a routine. You need to deftly recap on all of the main points in your essay without going over them all in depth. The last thing you want to do is repeat that which you have already written!

  • Do not introduce any new threads
  • Your conclusion is not the place to casually throw in any new threads that you have previously forgotten about. If you do suddenly remember something, then you will need to go back and introduce it into the main body of the work rather than trying to slot it in here.

  • Emphasize the significance of your findings
  • Unless you give credence to your findings, then your readers are going to be left scratching their heads and wondering what the point of it all is. If possible try and find a way of linking the literary work to the modern day, or you could maybe explain just why you feel so passionate about it and what it means to you. Whatever, your words need to resonate and connect with your audience.
