* Online Archive of California (OAC)

The OAC is a website that provides free public access to detailed descriptions of primary source collections (artwork, manuscripts, papers, historic photographs, and so on) maintained by more than 200 libraries, special collections, archives, historical societies, and museums throughout California — including collections maintained by the 10 University of California (UC) campuses.

The OAC is a core component of the University of California's California Digital Library (CDL) and is administered by the Digital Special Collections program.
