Sources
All of the data on player statistics came from Baseball Reference, an extremely informative search engine for baseball history. The contract data were more difficult to find, and so they came from a plethora of sources. While Baseball Reference was still useful, it was missing quite a bit of information on free agent contracts. As a result, I turned to old newspaper articles from sources like The New York Times and United Press International for contract data prior to 1991. For data after 1991, Cot’s Baseball Contracts (a branch of Baseball Prospectus) was used to gather free agent data. I also credit the National Baseball Hall of Fame and the Society for American Baseball Research (SABR) for a good amount of the information in this site. All these sources, among others, are listed beneath for reference.
