How Is A Historical Investigation Essay Different From A Literary Analysis Essay

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

Introduction

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.

Conclusion

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?

As the government begins its crackdown on essay mill websites, it’s easy to see just how much pressure students are under to get top grades for their coursework these days. But writing a high-scoring paper doesn’t need to be complicated. We spoke to experts to get some simple techniques that will raise your writing game.

Tim Squirrell is a PhD student at the University of Edinburgh, and is teaching for the first time this year. When he was asked to deliver sessions on the art of essay-writing, he decided to publish a comprehensive (and brilliant) blog on the topic, offering wisdom gleaned from turning out two or three essays a week for his own undergraduate degree.

“There is a knack to it,” he says. “It took me until my second or third year at Cambridge to work it out. No one tells you how to put together an argument and push yourself from a 60 to a 70, but once you to get grips with how you’re meant to construct them, it’s simple.”

Poke holes

The goal of writing any essay is to show that you can think critically about the material at hand (whatever it may be). This means going beyond regurgitating what you’ve read; if you’re just repeating other people’s arguments, you’re never going to trouble the upper end of the marking scale.

“You need to be using your higher cognitive abilities,” says Bryan Greetham, author of the bestselling How to Write Better Essays. “You’re not just showing understanding and recall, but analysing and synthesising ideas from different sources, then critically evaluating them. That’s where the marks lie.”

But what does critical evaluation actually look like? According to Squirrell, it’s simple: you need to “poke holes” in the texts you’re exploring and work out the ways in which “the authors aren’t perfect”.

“That can be an intimidating idea,” he says. “You’re reading something that someone has probably spent their career studying, so how can you, as an undergraduate, critique it?

“The answer is that you’re not going to discover some gaping flaw in Foucault’s History of Sexuality Volume 3, but you are going to be able to say: ‘There are issues with these certain accounts, here is how you might resolve those’. That’s the difference between a 60-something essay and a 70-something essay.”

Critique your own arguments

Once you’ve cast a critical eye over the texts, you should turn it back on your own arguments. This may feel like going against the grain of what you’ve learned about writing academic essays, but it’s the key to drawing out developed points.

“We’re taught at an early age to present both sides of the argument,” Squirrell continues. “Then you get to university and you’re told to present one side of the argument and sustain it throughout the piece. But that’s not quite it: you need to figure out what the strongest objections to your own argument would be. Write them and try to respond to them, so you become aware of flaws in your reasoning. Every argument has its limits and if you can try and explore those, the markers will often reward that.”

Fine, use Wikipedia then

The use of Wikipedia for research is a controversial topic among academics, with many advising their students to stay away from the site altogether.

“I genuinely disagree,” says Squirrell. “Those on the other side say that you can’t know who has written it, what they had in mind, what their biases are. But if you’re just trying to get a handle on a subject, or you want to find a scattering of secondary sources, it can be quite useful. I would only recommend it as either a primer or a last resort, but it does have its place.”

Focus your reading

Reading lists can be a hindrance as well as a help. They should be your first port of call for guidance, but they aren’t to-do lists. A book may be listed, but that doesn’t mean you need to absorb the whole thing.

Squirrell advises reading the introduction and conclusion and a relevant chapter but no more. “Otherwise you won’t actually get anything out of it because you’re trying to plough your way through a 300-page monograph,” he says.

You also need to store the information you’re gathering in a helpful, systematic way. Bryan Greetham recommends a digital update of his old-school “project box” approach.

“I have a box to catch all of those small things – a figure, a quotation, something interesting someone says – I’ll write them down and put them in the box so I don’t lose them. Then when I come to write, I have all of my material.”

There are a plenty of online offerings to help with this, such as the project management app Scrivener and referencing tool Zotero, and, for the procrastinators, there are productivity programmes like Self Control, which allow users to block certain websites from their computers for a set period.

Look beyond the reading list

“This is comparatively easy to do,” says Squirrell. “Look at the citations used in the text, put them in Google Scholar, read the abstracts and decide whether they’re worth reading. Then you can look on Google Scholar at other papers that have cited the work you’re writing about – some of those will be useful. But quality matters more than quantity.”

And finally, the introduction

The old trick of dealing with your introduction last is common knowledge, but it seems few have really mastered the art of writing an effective opener.

“Introductions are the easiest things in the world to get right and nobody does it properly,” Squirrel says. “It should be ‘Here is the argument I am going to make, I am going to substantiate this with three or four strands of argumentation, drawing upon these theorists, who say these things, and I will conclude with some thoughts on this area and how it might clarify our understanding of this phenomenon.’ You should be able to encapsulate it in 100 words or so. That’s literally it.”
