Simple and Easy Library Organization

Find the book you need, fast

New filters make it easy to find just what you need in a few clicks. Filter by every book on the Gospel of John, narrow to Reformed writers, then to commentaries, and add more filters to pinpoint just what you need.

Prioritize important books in searching

Have a few books you turn to again and again? Customize Logos to prioritize those resources when you search for something. So if you have a favorite commentary, lexicon, encyclopedia, or other book, Logos will show you search results from those books first.
