StackLife DPLA from the Digital Public Library of America (DPLA) demonstrates how the DPLA’s collection of books can be mashed up with other collections and browsed in highly innovative ways. Users can find and freely read 1.7 million books from the DPLA, the Biodiversity Heritage Library, the Hathi Trust and the Internet Archive’s Open Library.
StackLife DPLA also enables users to browse virtual bookshelves that cluster—and can instantly re-cluster—titles based on their multiple subject areas. With a click, a user can read the book online. The Harvard Library version of StackLife adds social features, lets users browse more than 12 million physical and digital items in the Harvard collection, and includes tools of use to a research community.
