Before you begin searching for sources for your literature review, it is helpful to know what a literature review is so that you include all the necessary sources. A literature review is a systematic examination of the scholarly literature about one's topic.
It critically analyzes, evaluates, and synthesizes research findings, theories, and practices by scholars and researchers that are related to an area of focus. In reviewing the literature, the writer should present a comprehensive, critical and accurate understanding of the current state of knowledge, compare different research studies and theories, reveal gaps in current literature, and indicate what is already known about the topic of choice.

A good literature review should be as comprehensive as necessary to identify all of the major works and debates on your research subject.
Subject-specific Databases - search in databases specific to your discipline of study to find more sources in your field. For example, Sociological Abstracts specializes in Sociology and will have more coverage of the sociology literature than an interdisciplinary, all-purpose database such as ProQuest. You should also search in more than one database/catalog since no one search tool covers everything. For example, if your topic involves education, consider also searching an education database, such as Education Fulltext.
Here are ideas about finding places to search.
Google Scholar - also search for your topic in Google Scholar. If you have a relevant source, consider searching the title in Google Scholar and using the “Cited By” link and the “Related Articles” to locate more literature. See also Bibliography Mining and Cited Reference Searching
Library Catalog - The Library Catalog also searches a variety of databases for books and journal articles at once. However, it does not search everything, so be sure to also look at disciplinary databases.
WorldCat - If your discipline publishes its scholarship in books, the WorldCat database is a place to look.
Bibliography Mining - use the list of works cited from a relevant source to locate additional related sources. This is a way to look for relevant sources published prior to the one in hand. A database may have a direct link to all the works cited, such as the example below; otherwise, you may need to look at each work cited manually.
Cited Reference Searching- search for items that have cited a relevant source. This is a way to look for relevant sources published since the item in hand was published. Disciplinary databases will often have this information.
Author Search - many researchers will write about the same topic for their entire career. Searching by an author's name in a subject database and/or Google Scholar may garner additional relevant information.
Subject Headings - also called descriptors, these terms are assigned to items to describe their content, or what they are about. Subject headings often facilitate more precise searching as they eliminate the need to search multiple phrases and synonyms for the same concept. Look for subject headings on items in the library catalog and in databases of journal articles. Many databases also provide a thesaurus, or index, of the subject headings used.
Beyond Vanderbilt - if you find a citation for a source Vanderbilt doesn't own, use Document Delivery/Interlibrary Loan (ILL) to get it. Articles and chapters can usually be scanned and sent electronically, but books must be mailed and typically arrive in 1-2 weeks, so plan ahead.
