The Gay, Lesbian, Bisexual Transgender Historical Society (GLBTHS) collects, archives and exhibits material that deals with the history of homosexuals and other sexual minorities. The main focus of the society is GLBT history in the United States of America, although it does also hold a few world sources as well. This well-designed site contains a lot of information about the society, with details of membership and forthcoming events and exhibitions. In addition to this there are two searchable online catalogues, which allow users to search the archive and manuscript content and the periodical holdings of the society, kept in their library and archive in Northern California. Also available is a comprehensive catalogue of web links, which includes coverage of other Western countries.
