The Digital Public Library of America (DPLA) is a large-scale, collaborative project with the goal of creating "a unique and consolidated digital library platform, ensuring America’s cultural and scientific record is free and publicly accessible online through a single access point, available anytime and anywhere.” The new platform delivers digital collections found in American archives, libraries, museums, and cultural heritage institutions to students, teachers, scholars, and the public.
In addition to performing as a one stop search engine to disparate collections, the portal also includes special features such as a dynamic map, a timeline that allows users to visually browse by year or decade, a feature to browse items by subject, and an app library that provides access to applications and tools created by external developers using DPLA’s open data. Noteworthy contributors include the Library of Congress, HathiTrust, and the Internet Archive. The project wasofficially launched in April 2013.
