These extensive collections document all facets of San Diego history, from the personal to the political. Collections such as the Ephraim W. Morse Collection and George White Marston Civic Collection provide a valuable chronicle of early San Diego business and civic developments. Collections of diaries provide intimate glimpses into the lives of San Diego citizens and their communities, such as late nineteenth-century Chinatown resident, Ah Quin or San Diego’s first female physician, Charlotte Baker. Archival collections may focus on particular people, businesses, clubs, events or on specific subject matter. The notebooks of E.H. Davis are invaluable to understanding San Diego’s Native American population and backcountry, while the San Diego County Water Authority Collection details the history of local water development. For more information: Archival Collections.
