About
The Digital Public Library of America (DPLA) is a nonprofit, open-access digital aggregator that unifies more than 53 million items from hundreds of partner institutions — libraries, archives, and museums — across the United States, making them freely available to anyone in the world. Through a single searchable portal, users can discover historical documents, photographs, audio recordings, films, and texts spanning American history, science, culture, and more. DPLA's curated Online Exhibitions bring thematic stories to life using primary sources, covering topics from the Space Race to the history of public libraries. Its Primary Source Sets are specifically designed for educators and students, providing topically organized collections — such as the Transatlantic Slave Trade or the Equal Rights Amendment — along with classroom-ready ideas. Genealogists can use DPLA's deep search tools to surface family history materials digitized from archives nationwide. For developers and institutional partners, DPLA offers a robust API and the DPLA Pro program, enabling the creation of custom applications and deeper integration with the network of contributing hubs. The platform regularly adds new partner hubs and continues to expand its collections. DPLA is ideal for K-12 educators, university researchers, genealogists, and curious minds seeking no-cost access to America's cultural heritage in a single, well-organized digital destination.
