Mentioned above:

The How and the Tao of Old Time Banjo, by Patrick Costello.

You can download a .zip at the link that unzips to the .htm web page version. Full book/CD versions also available for purchase, with goodies like video etc that would likely add to the learning experience. As noted at the download site, it's a fairly large book, so a "print your own" will probably cost you quite a bit more than just placing an order.

I was impressed, but then I'm not a banjoist; and the "banjo student friend" I saved it for was off into "some other style" at the time.

(Note to the author: I did a quick conversion to .pdf [Adobe distiller] when I downloaded the .zip, since .htm saves have a tendency to disintegrate when they get moved around in storage. I haven't done a full proof-read, but it appears to have come across okay. The file is 1,091 KB - about twice the size of the website .zip, but probably could be forwarded as an email attachment. It zips to 922 KB, which isn't really enough compression to be worthwhile(?). PM an addy or other contact info if interested? - I'd be happy to try to forward the .pdf if you'd have a use for it and don't already have it in "durable format.")
