On June 21, 2018, the Digital Public Library of America (DPLA) introduced Open Bookshelf, a one-stop shop for hundreds of e-books that are freely available online. This collection, which currently features over 1,000 books, includes titles that are in the public domain along with titles that are Creative Commons licensed. Visitors may browse this collection by language or genre (e.g. science fiction, education & study aids, and computers). Individual users can access Open Bookshelf through SimplyE, a free mobile application.
