Yearbook collectors - help
 

I have asked this question before and no one could help me. I have also reached out to others without success.

Years ago I had a copy, I think from SCD, of Yearbook variations. Some teams would issue a Yearbook at the beginning of the season and then issued another or perhaps more than one, if they made a trade. For example I have a 1951 and a 1953 Cubs Yearbook with supplement pages indicating they were issued later. Does anyone have a copy or know where I can find a listing of Yearbooks and variations? Thanks.
