Thompson's Compleat Collection
Thompson's Compleat Collection of 200 Favourite Country Dances

Currently, we have the first three of the four volumes, plus a few tunes from v.4. These were transcribed to PDF by Flynn Titford-Mock in 2007, and then transcribed to ABC by Andrew Kuntz in 2009-2010. You can find the PDF and some of the ABC files at the Village Music Project.
