The LGBTQIA Center's archival and manuscript collections can be found in the Library Catalog and in the Online Archive of California. There are also 21 GLBT Historical Society collections on deposit at SFPL.
All archival collections should be requested at the San Francisco History Center Reference Desk, 6th floor, Main Library. A sample of a larger collection of Harvey Milk/Joe Campbell Letters is available online.
In addition, the LGBTQIA Center pulp paperbacks, and video and audio recordings are available through the San Francisco History Center. Due to the rare and fragile nature of many of the materials, there are specific procedures to ensure the care of these items.
