As part of the Chorley (UK, North West) Slow and Steady session that happens every 1st Saturday in the month we have now produced a couple of "tune books" for use by the attendees. These have been produced by a group of us who run the sessions in our spare (?) time.
We have decided to license them in a free and open way, which means they can be downloaded from the website and used for whatever purpose you might wish. We'd like to know however.... 
We have something very similar a few miles down the road in South Manchester. Every second and fourth Wednesday evenings of the month are "tunes" nights at The Beech Inn in Chorlton. (The first and third Wednesdays are for songs). The tunes nights began just five years ago as "beginners sessions" with tune books on the tables for those who wanted them, though it has progressed well beyond that. People who consider themselves beginners are very, very welcome, of course. Yes, I know playing folk music from the dots is very much frowned on in some quarters, but it certainly gave confidence to those who could read music but were still learning to play by ear. Our tune book has gone through several editions, getting bigger each time. It's on the website
www.folkatthebeech.org as pdf, abc and midi. Also, as much as possible, the site shows clips on YouTube of people playing the tunes we use. You're very welcome to use what you find in the book. Oh, I have to say that I deny all responsibility for the chording in the book: my copy has
lots of scribbled changes to the chords to make everything melodeon-friendly.
If you're in South Manchester on a Wednesday evening we'd love to see you. Apart from the tunes and songs, at various other times the Folk At The Beech "brand" also has a ceilidh band, north-west clog lessons, excursions on folk trains, and route marches across the River Mersey for sessions in another pub.
