This app is essentially an alternative interface to the Open Library site — all of your data is stored there, and the books you read are hosted online, not in the app.
The moment you open the app and log in, any books you've already saved on the Open Library site are laid out on your screen.
You can sort them by title, author, publication date, and date saved, see which books are available to read, and open them with a single tap.
Open Library is an initiative of the Internet Archive, a 501(c)(3) non-profit, building a digital library of Internet sites and other cultural artifacts in digital form.
Open Library is an online library with millions of books to browse or check out.
