From the DPLA Blog:

The HathiTrust Digital Library will partner with the recently launched Digital Public Library of America (DPLA) to expand discovery and use of HathiTrust’s public domain and other openly available content.

“HathiTrust’s joining the Digital Public Library of America more than doubles the size of our unified collection, and—as so many have asked for—fills it with millions of books. We couldn’t be more delighted. Over the last five years, HathiTrust has built an incredible digital infrastructure to store the scanned holdings of its many university and library partners, and we in turn look forward to providing a large general audience for these valuable works, and new pathways into them,” said Dan Cohen, DPLA’s Executive Director.

According to HathiTrust Executive Director John Wilkin, the partnership reflects the complementary nature of the two organizations. “The first priority of HathiTrust has always been preservation,” he said. “But to fulfill the preservation mission, we must provide access: content that can’t be found and used risks being forgotten.” Wilkin stressed that HathiTrust will continue to enhance its own discovery and access platform, first launched in 2008. But DPLA puts HathiTrust’s collection before a broader audience, alongside innovative search and use tools, including timelines, maps, and a growing number of apps.

Of HathiTrust’s nearly 11 million volumes, the metadata records associated with the almost 3.5 million that are freely available will be accessible on the web at dp.la, and through the DPLA application programming interface (API), making HathiTrust a DPLA “content hub.” (The digitized volumes themselves will continue to reside in HathiTrust.) The partnership makes HathiTrust the single largest DPLA content hub, in the company of institutions such as the Smithsonian, the National Archives, the New York Public Library, and many others.

[Our emphasis] The partnership officially begins today, June 18, 2013, and the data is in the process of being transferred from HathiTrust to the Digital Public Library of America. DPLA will be working to add a special interface for books to supplement its novel map and timeline browsing interfaces, but the HathiTrust content will be available through the current site as soon as the data is loaded.
