Book Sources

When you add a book, Find a book searches free catalogs of public-domain books and audiobooks. You choose which catalogs it searches in Settings → Library → Book sources.

Source	What it has	On by default
Project Gutenberg	Ebooks	Yes
Standard Ebooks	Ebooks with carefully prepared text and cover art	Yes
Wikisource	Ebooks. Rights differ per work, and Nostos shows them for each one	Yes
LibriVox	Audiobooks read by volunteers	Yes
Litteraturbanken	Swedish literature	No

Turn a source off and it disappears from Find a book until you turn it back on. Books you already imported from it stay in your library. An imported book is a normal Nostos book and does not depend on the source after the import.

Litteraturbanken is off by default because it has not confirmed that it allows automated access. When you turn it on, Nostos only offers its works that the source marks as CC0, public domain or CC BY.

Each source shows its rights notice in Settings. Public domain in the United States is not the same everywhere, so check the rights in your own country before you rely on them.
