"A Biographical Index Of Music" (including web links) is at 360,000 words and 2100 pages, all searchable for any name, title, genre, instrument, or term in music history, and it's only 3.3mB.

I've been working on this for 18 months, and it's finally starting to look good. I'm halfway through a 700-page music encyclopedia, gleaning new entries, and I've got one more church hymnal at the bottom of the pile to check yet (for any titles or artists I've somehow overlooked so far). I'm also adding search links for Wikipedia and YouTube, and expanding entry notes.

I'm giving it away to anyone who wants it.
