What and why?
A literature review is...
  • a systematic and critical analysis of the literature on a specific topic 
  • it describes trends, quality, relationships, inconsistencies and gaps in the research
  • it details how the works enhance your understanding of the topic at large

Keep in mind...
  • it is not simply an annotated bibliography that summarizes and/or assesses each article
  • there is not one, correct way to approach and write a literature review 
  • it can be a stand-alone paper or part of a thesis/dissertation 
  • format and requirements can vary between disciplines, purpose and intended audience

Why do we write literature reviews?
  • they provide a depth of knowledge of the field of inquiry: facts, theories, important scholars, trends, etc.
  • to gain understanding of methodologies common to the field and appropriateness of various methods
  • to help us understand what is known and what is unknown in the field
  • to help us to determine scope of your question. Usually it will help to narrow or focus a problem/issue, but it may also help you determine where you need to step back and look at a bigger problem/question/theories/etc.
  • Reinforces that your proposed question is a meaningful contribution to the field
  • Generates hypotheses or questions for further studies
Conducting a Literature Review
1. Choose a topic and defining a question
  • Initially, keep your topic fluid, and do preliminary searching so you can adjust your question/scope as necessary
  • Use reference tools like Gale Virtual Reference Library to make sure you’ve grasped theories and “big pictures”
  • Once you have a sense of the literature landscape, try to focus on an answerable question, rather than covering a broad topic
  • Determine inclusion criteria and parameters and depth of coverage: highlights vs. comprehensive review, current research vs. seminal works, limit to specific populations, applications, methodologies, etc.
2. Identify the Literature
  • Determine which search tools you will use. Don’t use just one!
  • For each search tool, determine the search phrases and limits that will provide the best results. Save or document this search!  The best search for one database isn’t likely to be the best search in another database
  • Through this process, adjust your topic and/or keyword scope accordingly
  • Know that you may need to conduct multiple searches in each database to catch all of the literature on your topic
  • Consider searching for distinct sets of literature that will each enlighten your knowledge of a very specific topic
  • Try to identify the “seminal works” and important authors for your topics
  • Save your searches and /or keep a list of subject headings or keywords related to your topic.  You may rely on these in further searching and in developing conceptual outline for your review
3. Analyze the Literature
  • Read the articles you’ve selected
  • Take notes!  Focus on the strengths and weaknesses, as you are aiming to provide a critical analysis, rather than a summary of the literature
  • If your notes use the exact phrasing as the article, note it as such to avoid plagiarism
  • Consider categorizing the articles, or parts of articles, as to which aspects of your topic they address
  • Note any jargon, definitions or theories you want to use, remember or investigate further
  • Identity commonalities, relationships and trends in the literature. This may help determine themes or categories for your review. Also note any inconsistencies, so you can later determine if there is cause for specifically addressing them in your review
  • Note any gaps in the literature, and consider why this may be occurring
Choosing a Database
1. Start here
2. From here, you may access the databases in a variety of ways…
  • Browse alphabetically for a specific database
  • Choose “Databases by Subject” to see databases recommended by areas of study
  • Choose “Databases by Type” to see databases with specific types of material (ebooks, statistics, images, etc)
3. To determine which databases are best for your topic….
  • Look at the “About” pages for each database to determine what is included
  • Look at the recommended databases list for each subject
  • Find the subject librarian/s for areas related to your research and ask for recommendations
Tips:
  • Don’t search with your topic as a phrase! (i.e.: faculty stress related to tenure processes)
  • Use ANDs to separate important concepts – often this is done by typing each concept into a unique search bar.
  • Use ORs to connect synonyms within a search bar.  Think of all the terms that might fall under the umbrella of this concept (stress OR coping OR anxiety).  
  • When you find a good article, look at the subject headings and adjust your keywords accordingly.
Example search:
sample search in database
Google Scholar
  • When off campus, use the Google Scholar link in the Libraries databases list so that Google will recognize you as a UT user and link you to our subscriptions
  • This link google scholar get this article link works like find it at ut button in the databases
  • Google Scholar searches within the full text of most articles, so very general searches will retrieve many, many results
  • Use the arrow in the search box to see advanced search options:
    arrow in google scholar search bar opens advanced search
  • The advanced search will help narrow your results:
    google scholar advanced search
     
Using Citation Counts
Some databases will show you how many times an article has been cited by others, so you can get an idea of its effect on the field.

Google Scholar's citation count will give you a good idea of how many times an article has been cited, but don't consider it completely accurate
google scholar citation count

Web of Science is a more accurate measure, but is stronger in the sciences than in the humanities. Use the limiters on the bottom of the search page:
web of science limiters
Citation counts appear under each article's description:
times cited in web of science

You may stumble upon this feature in some other databases, so keep an eye out.
