From the annoucement:
Researchers are now able to explore Calisphere’s incredible collection of digital primary sources within the Digital Public Library of America (DPLA). This month, the CDL successfully shared more than 225,000 metadata records from Calisphere from UC libraries and over 120 other libraries, archives and museums in California with DPLA. In addition, another 112,000 from the collections of the San Francisco and Los Angeles public libraries were shared as part of a pilot to grow the number of California contributions. As a result, visitors to the DPLA website will now be able to discover important digital collections from across California, amidst a large and growing national aggregation. DPLA currently provides access to over 10 million items contributed by 1,600 institutions nationwide.
