The Prelinger Library is an independent research library located in San Francisco’s South-of-Market neighborhood. It is open to anyone for research, reading, inspiration, and reuse. The library is primarily a collection of 19th and 20th century historical ephemera, periodicals, maps, and books, most published in the United States. Much of the collection is image-rich, and in the public domain. The library specializes in material that is not commonly found in other public libraries.
