Major league baseball is an industry that involves billions of dollars of substantial investments, including those in player salaries, litigation, capital investment into stadia, and so on. This compelling site, developed by Maury Brown and Gary Gillette (the co-chairs of the Business of Baseball committee of the Society for American Baseball Research), provides a host of data on the "business end" of professional baseball. First off, there is the data section of the site, which includes detailed player salary information from 1985 to 2004, arbitration results, franchise valuation information, and league attendance from 1884 to 2004. Next there is the section that provides details on new stadium construction and on those stadiums currently being renovated. The site also contains additional articles on a wide variety of baseball-related topics and an interview section, where users can read well-thought-out Q&A sessions with such baseball luminaries as Bowie Kuhn and sports economist Andrew Zimbalist.
