Mike - I hope that you are getting your information from The Encyclopedia of Minor League Baseball.

I love that book! However, the newer hardback edition leaves out all the 'this day in the minor leagues' notes...which is so full of great stories.

I had sold my paperback copy with all the stories when I had the new one on the way. I had to scramble and find another copy...so now I have both.

I HIGHLY recommend this book to all - it contains the most 'new' information and lore I had 'soaked up' since the original Bill James Abstract.
