The archival collection now known as the John J. Wilcox Jr. GLBT Archives of Philadelphia was originally established in 1976 and has been housed at the William Way Lesbian, Gay, Bisexual and Transgender (LGBT) Community Center since 1997. Dedicated to documenting Philadelphia's LGBT community, the collection consists of books, periodicals, organizational records, personal papers, ephemera, visual materials, and sound recordings concerning sexual minorities, the gay/lesbian rights movement, and the history of sexual minority communities with an emphasis on Philadelphia and the Delaware Valley. There are also materials on the women's movement of the 1950s to 1970s. The archival materials total nearly 300 linear feet of materials from 1918 to the present (most are from 1960 to the present).
