Dwight has available his tab book volume 1, titled:

Yew Piney Mountain: Obscure Underground Clawhammer Banjo from Mysterious Central West Virginia with CD, pictures, tunes, tablature and stories Vol 1. This book can be purchased from Morning Star Folk Music

Gordon Banks is a student of Dwight's who doesn't use tab, but he's found that it can be useful for some who like to use it as a reminder of how a tune goes and has generously donated some tabs that he has worked out from Dwight's playing.

Stewart Seidel, another long-time student of Dwight's, has been in the habit of tabbing out everything Dwight taught at every class he's ever been to for more than a decade. If you want to experiment with these tabs, they are available here as TEF files for viewing with the free TEFView program.
