The Digital Public Library of America was launched today. Led by Executive Director Dan Cohen, the DPLA may very well become the modern answer to the Library of Alexandria -- the ancient world's most extensive knowledge center. At present, the library contains over two million items in multiple formats (texts, pictures, movies, etc.) drawn from the collections of multiple partner institutions including the New York Public Library, the Smithsonian Institution and the Minnesota Digital Library.
Developers can use the DPLA's API to create apps and users who create an account can create lists and save items from their searches.
The DPLA also allows users to access its collection with a timeline feature and has developed a number of exhibitions including one on the Bread and Roses Strike of 1912.
We expect many more good things to come from this undertaking.
