This book was compiled by Cari Fuchs, concertina/hammer dulcimer player, formerly of Pittsburgh and now from the Boston area.

There are settings of many common tunes, so it's a good general resource for session tunes. Only cautionary note- it's got a few peculiarities in the settings here and there because of the instruments she plays- a fiddler or whistle player might have done it just a bit differently. Also, variations are sometimes a little confusing.

I think overall it is a good resource and worth purchasing if you don't have a similar collection.
