How about an electronic copy of your guide on say excel with each bit of info in a seperate column ?
that way you could filter, sort by artist, title, label, price whatever takes your fancy.
i'd happily pay as much for this as I would for a hard copy and you don't have the printing costs.
and while i'm at it you could give me a copy of your sales history database for coming up with the idea.
