Last week the Digital Public Library of America went live for the first time. Launched by Harvard's Berkman Center for Internet and Society, this website aims to become a one-stop-shop of digitized materials from libraries, museums, archives, and universities, completely free and open to the public.
The project has received support from a number of different funding sources, including the National Endowment for the Humanities and the Institute of Museum and Library Services. The amount of material on this platform will continue to grow over time, but already it brings together in one place a wealth of materials from the Smithsonian, the National Archives, the New York Public Library, the University of Virginia, and Harvard, among other places. The materials include books, images, videos, manuscripts, and oral histories. I haven't had a chance to do much browsing of Civil War resources on the website yet, but it will certainly become a valuable tool for online researchers.
