A catalog is a library’s shelf you can search and download from inside Ledgable. Open Book catalog (Settings › Books), tap 📚 Free catalogs for the ones marked ★, or paste an address below.

Classics and the public domain

• ★ Project Gutenberg — over 70,000 free ebooks, mostly older classics.
  https://www.gutenberg.org/ebooks.opds/
• Wikisource — texts volunteers have transcribed, ready as ebooks (English).
  https://ws-export.wmcloud.org/opds/en/Ready_for_export.xml
• Standard Ebooks — beautifully made public-domain editions. Its catalog is for its patrons; anyone can download the books from standardebooks.org and add them as files.

Open books

• ★ Unglue.it — books their authors made free to read and share.

• Internet Archive — a huge collection; some books need a free archive.org account to borrow. It can be slow to answer.

Tips

• Your public library may have a catalog too — ask for its OPDS address.
• Books you download land on your Bookshelf and sync like any other book.
