While the study of gender and sexuality is constantly evolving, the standardized Library of Congress system of subject headings often lags behind what might be the most current or obvious subject term.
You need to be flexible in how you go about searching for relevant secondary sources on sexuality. Keep in mind a wide range of possible search terms in the course of your search. Examine carefully what specific subject headings come up in both older and newer books on your topic.
A good strategy for a comprehensive search is to use keyword searching to find some books on your particular subject; then look at their records to see what standard subject headings were applied to the item; and follow up with a subject search on those terms. The advantage of subject searching is a more comprehensive search result due to the fact that librarians work hard to determine the main topics and then to assign the correct standardized terms to each item they catalog.
The University at Albany Libraries has created an online list of Subject Headings for LGBTQI Research. These subject headings are useful for looking up topics related to gay and lesbian studies.
