The mission of the Lambda Archives of San Diego is to collect, preserve, and share the history of lesbian, gay, bisexual, transgender and queer people in San Diego, Northern Baja California and Imperial County region. Although most of the collections date to post-1970, there are original materials dating back to the 1930s. History is best reflected in the records and cultural artifacts of those people who are directly involved in its events. Lambda Archives is dedicated to preserving and interpreting this important historical material and making it available for learning.
The Lambda Archives of San Diego's digital collection at California Revealed consists of moving images and audio recordings from the 1970s to present day. The recordings in this collection focus on the LGBTQ community in California and include tapes from Out in San Diego, an LGBT radio program that aired on KPBS in the mid-1980s, as well as interviews from the Lesbian History Project, and a series of oral history interviews with prominent members of the LGBTQ community in San Diego.
