Denver LGBTQ+ Archives: Where to Research Queer History

Denver LGBTQ+ archives sit with four institutions: the Denver Public Library, History Colorado, the Center on Colfax and the University of Denver Libraries. Start with the Denver Public Library for paper records, move to the oral histories for first-person accounts, and use the University of Denver portal when the research has to happen online.

The Denver Public Library LGBTQ research guide is the first stop for organizational records and personal papers. The library holds records of Equality Colorado and other community groups, along with personal papers of LGBTQ Coloradans.

The collections cover HIV/AIDS, support groups, activist organizations and social clubs. The publications Big Mama Rag and Out Front are part of the holdings. For Denver LGBTQ history research built on organizations, this is the strongest starting point of the four.

The Gill Foundation LGBTQ+ Archives at History Colorado are described as the first permanent LGBTQ+ collection at a state history institution in the United States. The archives overview says the collection spans the territorial era to the present. That makes it the widest in time of the four, and it suits researchers following Colorado queer history from its earliest decades forward.

The Colorado LGBTQ History Project is a program of the Center on Colfax. It was established to collect and preserve oral histories from LGBTQ Coloradans, archive them and make them available to the public.

The oral histories are digital recordings listed in an Oral Histories Catalog, so a researcher can begin from a desk. Questions go to history@lgbtqcolorado.org. The project's funding comes from The National Trust for Historic Preservation's Telling the Full History Preservation Fund, with support from the National Endowment for the Humanities.

For the organization behind the project, see The Center on Colfax.

The University of Denver Libraries guide is a portal for researching LGBTQ populations and issues, both contemporary and historical. It lists two resources:

• Archives of Sexuality & Gender: LGBTQ History and Culture
• Digital Transgender Archive: an online hub for digitized historical materials

Both are online, which makes this the route for researchers who cannot travel to a reading room.

Two pages on the site give context for what these archives document. Denver LGBTQ+ History Before Stonewall: Early Queer Venues covers early queer venues, and Denver LGBTQ+ Rights History: A Legal Timeline lays out the legal timeline. Read either one before opening the archives to know which organizations and eras to search for.
