Big Mick, WoW! Ambitious. Great idea.

John in Kansas, I've been indexing my Gaelic Song books. I'm putting them alphabetically by title, and each column has the title of the book (abbreviated of course), with the page number. Sounds similar to your plan. This way I can look up in a single place which book a particular song is in. As a benefit, I have noticed that some songs are much more popular than I had even thought.
