Does anyone know...

I have collected publications for over 40 years and there are no really good guides especially when it comes to process.

I think the greatest thing that has ever happened for pub collectors is eBay. You get to see and save photos and the prices realized on eBay are the real price guide.

If you are collecting scorecards it the best way to catalog the different variations for clubs each year. There are several very good baseball yearbook checklists that have floated through the hobby over the years. If you collect media guides the late Joe Cronin did a wonderful checklist of when each team first issued a guide or just the folded rosters for each season.
