I have hardcopies of all three books, but I still find it worth spending the extra to get this app.I’d be more than happy to spend extra to get an upgrade that has book 3 in it.

The dirty secret of music is that in any band of amateurs, there's going to be at least 1 individual with illegal copies of the music. The sheets are expensive, but nobody's getting paid and not everybody's able to lay out $40 for all the books needed. So a moral compromise creates harmony in the short run. Here, Transported Products has made sure none of that hanky-panky will go on with its app. Exported shares are encrypted and expire after 2 weeks; 15 screen shots will freeze the app entirely. I would be happier if I thought Peter Barnes, the excellent author and compiler of the work, got the lion's share of the $40 price, but I doubt it. So give yourself some flexibility and buy the print copies, not this. (Previous review disappeared, likely my error)

I have only been using this quite a while and am impressed with its ease of use and flexibility in using different sources and annotating the tunes.Also great with other tune and dance description collections. Easy to make and edit gig lists. Great!
