The librarians at Mina Rees are excited about the launch of the Digital Public Library of America (DPLA). In addition to coordinating on a regional/hub basis the ingestion of many digital collections, the DPLA hopes to extend libraries’ traditional orientation around access, by using Creative Commons type licensing and providing API‘s so other constituencies can re-display content within their own platforms.
