Alexandria is a library. It provides a searchable and readable archive of (primarily) fanfiction from several sources on the wider web. Alexandria presents a cleaned version of the source (for example, it attempts to normalize all scene breaks). It tracks which fics you've read, and where you left off in each one.
It dos not yet have much functionality for discovering new stories to read. There's currently a limited set of stories rated by our first librarian jac. In the future automatic suggestions based on user ratings may be available.
Offline reading through epub export and other means is planned.
