My Banjo Bible

 The Banjo Player's Songbook: Over 200 great songs arranged for the five-string banjo by Tim Jumper (Author), Peter Pickow (Editor)

In actual fact I've got two banjo bibles and they are both by Tim Jumper. The other is How to Play Banjo which was the first tutor book I got and it covers the basics of both fingerpicking and frailing. The Banjo Players Songbook though is my go to for basic versions of most of the popular banjo songs in a frailing style. It gives you the bare bones of the tune and a bit of background over which you can elaborate as you wish. Recommended.
