Find articles by important authors in your field and follow who has cited them and other authors they have cited. This database does not include all counseling and psychology literature, so it works well in conjunction with Google Scholar.
Find dissertations on your research topic by searching for key terms in the abstracts of dissertations, or search for other dissertations from GW or from your advisor. Most dissertations have literature reviews, which can be very helpful to your own lit review. The database includes the full text of dissertations from 1997 to the present.
Search for books and articles with key terms, or paste in the title of a book or article and search. Under the article or book title in the results list, click on "Cited by" to view other titles that have cited the article or book.
