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 the Imperial County region. Although most of the collections date to post-1970, there are original materials dating back to the 1930's. 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.
