If you’re thinking about earning your PhD or another type of doctorate degree, you may be wondering, What is a lit review? And What is the purpose of a literature review? A literature review, or lit review, is an important component of developing a dissertation for a doctoral degree program.
When approaching a literature review, doctoral learners are typically either overwhelmed by the scope of the task or they may underestimate the importance of it. The College of Doctoral Studies at Grand Canyon University has compiled some guidance on the importance of a literature review and the essential elements of a well-written, scholarly lit review.
In This Guide:
For doctoral learners, the process and purpose of writing a literature review provides an opportunity to become steeped in the intricacies of the chosen topic of research, the prominent researchers in the field and the trends and theories associated with the topic. This process is not to be underestimated for its complexity and value to the dissertation.
The literature review brings to the forefront all current research and information to develop an understanding of the chosen field. It connects the learner to their future research “peers.” The learner can expect to expound on or follow up on the most notable researchers in the field as part of the literature review.
A great literature review will also pinpoint the research that’s needed to make advancements and build off what’s already known. View everything you’re reading with a critical eye. For example:
Using these questions to guide continued research helps us answer: What is the purpose of a literature review?
According to Boote and Beile’s (2005) journal article, when examiners encounter a poorly written literature review, they are alerted to thoroughly examine the methods of data collection, the analysis and conclusion more carefully. They contend the entire dissertation is negatively affected in the quality and conceptual framework; thus, a weak dissertation is likely the result of a poorly written literature review.1
In essence, the literature review gives the learner a solid idea of scholarly research and its trends, which point to areas of further research. Synopsis of the reading and review demonstrate the learner’s understanding of the research topic. The learner can begin to hone the overall topic and refine the area of interest. Reading empirical and theoretical literature is key.
If one were to put together a formula for an effective and scholarly lit review, it might look like this:
Specific topic + critical analysis + synthesis = literature review
Like any standalone piece, a lit review should have a definable structure. The basic elements of a literature review are the introduction, body and conclusion. Since a lit review for a dissertation is not a standalone piece, the introduction and conclusion may only consist of a few sentences each.
Here’s a look at how to write a literature review:
Throughout each of these elements, you should strive for the following attributes:
In addition to including important elements, consider mistakes to avoid when learning how to write a literature review, including the demonstration of scholarly bias. Alternative theories, interpretations and points of view are typically excluded. Additional mistakes to avoid include:
What is a lit review? This is an element of a dissertation that is often misunderstood.
For some, the literature review is interpreted to be a short summary of articles the student has read or a synopsis of readings in the field. While this might be a part of the process, it is not a complete literature review. A well-written literature review is pivotal to the writing of a solid dissertation. It should provide a comprehensive, coherent overview of significant literature on a specific scholarly topic. This entails the review of scholarly, peer-reviewed articles, books, abstracts, reviews, dissertations, websites and any other available resources to formulate a critical analysis of the information compiled.
In other words, a summary of literature in the field is not sufficient by itself. A scholarly analysis is one of the most important elements of a literature review. Included in this analysis is a brief historical description of a topic, isolation of a theory/conceptual framework and a well-written critical evaluation of the work. Reviewing the literature brings the general idea for future research into focus, thereby making the gap in scholarly literature more clear.
