If you’re unfamiliar with literature reviews, going to college would give you a crash course on them – but not in a good way. Most students get sick of hearing the word ‘literature review’ thrown around in college classes and never get to know what it truly requires, let alone where to start.
Not to worry – we’ve got you covered with this stepwise guide to writing a dissertation literature review. We’ll cover some literature review basics and discuss its forms, so let’s get started.
What is a literature review?
Conducting a literature review requires a critical appraisal of the sources you have acquired and read about around your topic. The review helps identify a “gap” in the literature that your study will aim to fill.
Since there are many misconceptions regarding what a dissertation literature review entails, let’s start with a clear definition. A dissertation literature review is a straightforward summary of relevant sources in a dissertation. It often demands you to critically engage with the material to express your favorable or negative ideas about it.
Overall, a dissertation literature review demands extensive critical thinking to discover new perspectives and address gaps in the literature. You’ll need to ask questions like; what is my take on a certain source? Is this interpretation significantly different from other points of view in the literature? And many others.
The primary goal of a literature review dissertation is to summarize and give a critical critique of the research arguments discovered in your readings without adding anything new to the literature.
How long should a literature review be?
The solution to this question is not a specific one. The literature review length varies based on its audience, the objective, and the student’s degree of education. For example, a literature review produced by an undergraduate is always shorter than those submitted by Ph.D. students, and for essays, it’s even less.
That said, the length of a dissertation literature review should be between 20 and 40% of the total project length. So, if you are asked to write a 10,000-word dissertation, you should provide a minimum of 2,000 words for the literature review. Regardless of the length of the literature reviews, make sure you stick to the correct literature review outline to score top marks.
Types of literature review
Primarily, your discipline determines the type of literature review you’d get to write. Performing an assessment work in your undergraduate studies, publishing a study in a journal, or working on your Ph.D. heavily influences the style of literature review you conduct.
A literature study for an undergraduate degree subject will not be as extensive as a literature review for a Master’s or Ph.D. thesis. There are about four common types of literature reviews.
1. Narrative literature review
It identifies and evaluates published material on a wide topic. A wide range of relevant issues might be included. The review results are often reported in a narrative format.
2. Critical literature review
It answers particular, patient-oriented questions that often emerge in real-world practice.
3. Systematic literature review
It attempts to find, evaluate, and synthesize research findings to improve decision-making and define best practices. The technique varies depending on the type of study, which might include studies of efficacy, prevalence, qualitative research, etiology, diagnostic test accuracy, or economic assessment.
4. Abstract literature review
The abstract of a source is quite useful in literature review research. However, abstract literature reviews, on their own, focus on less particular and critical reviews.
