"The vision of a national digital library has been circulating among librarians, scholars, educators, and private industry representatives since the early 1990s. Efforts led by a range of organizations, including the Library of Congress, HathiTrust, and the Internet Archive, have successfully built resources that provide books, images, historic records, and audiovisual materials to anyone with Internet access. Many universities, public libraries, and other public-spirited organizations have digitized materials, but these digital collections often exist in silos. The DPLA  brings these different viewpoints, experiences, and collections together in a single platform and portal, providing open and coherent access to our society’s digitized cultural heritage.

The DPLA planning process began in October 2010 at a meeting in Cambridge, MA. During this meeting, 40 leaders from libraries, foundations, academia, and technology projects agreed to work together to create “an open, distributed network of comprehensive online resources that would draw on the nation’s living heritage from libraries, universities, archives, and museums in order to educate, inform, and empower everyone in current and future ­generations.”

In December 2010, the Berkman Center for Internet & Society at Harvard University, generously supported by the Alfred P. Sloan Foundation, convened leading experts in libraries, technology, law, and education to begin work on this ambitious project. A two-year process of intense grassroots community organization, beginning in October 2011 and hosted at the Berkman Center, brought together hundreds of public and research librarians, innovators, digital humanists, and other volunteers—organized into six workstreams and led by a distinguished Steering Committee—helped to scope, design, and construct the DPLA.

The DPLA is led now by Executive Director Dan Cohen and guided by a Board of Directors comprised of leading public and research librarians, technologists, intellectual property scholars, and business experts from around the country. Based in Boston in the historic Boston Public Library, DPLA has grown from an initial staff of four to nearly ten, including an in-house technical team.
