Digital Public Library of America was launched in April 2013. This is an amazing resource which is described below in a description from their webpage. It is all free and expands the resources available from any single library or museum. We share it here for your enjoyment.
What is the DPLA?
The Digital Public Library of America (DPLA) brings together the riches of America’s libraries, archives, and museums, and makes them freely available to the world. It strives to contain the full breadth of human expression, from the written word, to works of art and culture, to records of America’s heritage, to the efforts and data of science. The DPLA aims to expand this crucial realm of openly available materials, and make those riches more easily discovered and more widely usable and used.
