Use bibliographies from the background sources to identify books on your topic. Use the authors and titles of these books as well as key words and topic phrases you identified earlier to look up books on the BYU Library Catalog. Find published bibliographies on the catalog by doing an “Advanced Search.” Put keywords from your topic in the “Keyword” field. Then type the word “bibliography” in the “Subject” field. For current bibliographies check Bibliographic Index: A Cumulative Bibliography of Bibliographies (New York: H.W. Wilson, 1937-), Gen Ref: Z 1002 .B595. Published in April, August and December, this is organized by detailed subject categories. Index includes not only separate published bibliographies, but also bibliographies from books, pamphlets, and journals.
