From Calisphere:
Calisphere provides free access to more than 2,000 collections digitized and contributed by all ten campuses of the University of California and more than 300 cultural heritage organizations (libraries, archives, and museums and historial societies ) throughout the state. Each of these organizations has specific collection emphases, which may be informed by local history, activities, research interests, or other topics significant to its communities.
Learn more about the collections in Calisphere, including how primary source records are described; how shared community values and standards guide access to historical materials; and, how they strive to provide responsible access to digital primary sources.
