Identifying and obtaining the relevant literature

When trying to answer a technical question, identifying and obtaining the relevant literature is only
part of the solution process. The next step is to consolidate that information into a form that is
maximally useful – the review should summarize and critically evaluate the information. For this
project, you will write a literature review using the sources you accumulated before.
Background*
A literature review is meant to ask and answer: what do we know – or not know – about this
particular topic? How well you answer this question depends upon:
• • the effectiveness of your search for information,
• • the quality and reliability of the sources you choose, and
• • your ability to synthesize the sources you select.
To assess the quality and reliability of your sources, consider the following four aspects of the
literature you found:
• 1. Author a. Assess the authors’ expertise and credibility by looking at citations, articles, and
books by this author to find information about who the author is, what his/her credentials are, and
what occupation or position s/he holds.
•
• 2. Publication and Audience a. Examine the publication for which the author is writing to
determine the author’s intended audience, and the publication’s reputation, credibility, and target
reader/researcher.
• b. Look in the text for clues to what audience the author is addressing, e.g., specialized or
general vocabulary, types of sources cited, explicit references to the audience.
• c. Look at the publication itself: front/back cover, submission guidelines, editorial board,
etc., for an indication of audience and types of articles. Once you’re satisfied that your source is
credible and reliable, you are ready to analyze the text itself.
•
• 3. Argument/Evidence a. Carefully read the text, looking at the evidence the author is using
and the structure of the argument (e.g., whether it moves logically from point to point).

(http://guides.library.vcu.edu/lit-review/101).
b. Identify the range of evidence (personal opinions or observations, research, case studies,
analogies, statistics, facts, quotations, etc.).
c. Assess how the author presents and discusses alternative perspectives in relation to his/her
thesis?
d. Locate any gaps or inconsistencies in the development of the argument.
a. Analyze the text in relation to your question and developing thesis, and in relation to other
sources you’ve been reading.
