Digital Public Library of America: The DPLA is a discovery tool, or union catalog, for public domain and openly licensed content held by the nation's archives, libraries, museums, and other cultural heritage institutions. It was started by Harvard University's Berkman Center for Internet & Society in 2010, with financial support from the Alfred P. Sloan Foundation, and has subsequently received funding from several foundations and government agencies, including the US National Endowment for the Humanities, and the Bill & Melinda Gates Foundation. It "aims to unify such disparate sources as the Library of Congress, the Internet Archive, various academic collections, and presumably any other collection that would be meaningful to include.
They have yet to decide such issues as how near to the present their catalog will come. There is an ongoing dispute regarding so-called 'orphan works' and other questions of copyright." John Palfrey, co-director of the Berkman Center, stated in 2011: "We aspire to establish a system whereby all Americans can gain access to information and knowledge in digital formats in a manner that is 'free to all.' It is by no means a plan to replace libraries, but rather to create a common resource for libraries and patrons of all types.”
The DPLA links service hubs, including twelve major state and regional digital libraries or library collaborations, as well as sixteen content hubs that maintain a one-to-one relationship with DPLA.
