Lipset's encyolopedia cross references t206 with the silks, t3s, and other sets along with a t205 cross-reference. It's a nice resource for a type collector.

Not long after I first started collecting t206 in 1999, I pick up Mark Peavey's short work on T206 and it helped me out a great deal too. In fact, I still use it for a check list. One time, I gave it away to a new collector and Mark sent me a new one for free. Nice guy.
