Ted ZanidakisA recent similar style pamphlet to Heitman's book is
available. "The Mysteries of T206" by Mark Peavey (2001).
It usually appears on the T206 listing on Ebay. And, it
costs less than $10. In comparing the Heitman book with
this newer one, I find the Peavey version somewhat easier
to read, Both books are very detailed and informative on
the T206 set.
