Two additional data sources have been added to Tellico. Freebase is a generalized database of just about any structured data anyone can add. Tellico can search Freebase for books, comic books, movies, music, video games, and board games. Open Library is a online book database that aims to have one page for every book ever published.
Both sites return data in the JSON format, so the QJson library is required when compiling. These data sources will be available in Tellico 2.3.
