Hi - Does anyone know a good source for information on MLB farm teams going back to the early 1970s. As I continue research various GU jerseys from the 70's and 80's, I have found it to be increasingly beneficial to further research certain minor league teams in order to ascertain whether a jersey was possible recycled to the farm teams. Ideally, some sort of team/club directory would be good. At least it's a starting point.

Thanks
