I have the MCO editions 4 through 15.  I'm trying to locate the three earlier ones.

They don't have to be great - just decent.  Thanks, Grzenda

Thanks for the input on MCOs. 

http://www.chessbooks.co.uk/  is Tony Peterson.  I got MCO4

from him in very good condition at a very fair price, but he doesn't have any of the earlier ones.  I looked at the other web site noted, but didn't find anything.  If any other source occurs to you, please let me know. 

Try this one:

Carl;

      Thanks for your input.  Thats a beautiful search engine!  But, the only early

edition it came up with was the 2nd for $200 - out of my league. 

      If you run into anything else, please let me know.
