As a fall out from my card collecting, I started collecting prewar baseball record / guide / "dope" booklets. All of what I've collected to this point has come from eBay, but I've never been able to find an information source on what exists, or an "expert" that knows what might be out there. Several examples of what I have are shown below. Who might be the person to talk to in this area or is there a resource that might list the years and what was printed?1908 Newark Evening News - "Just Baseball" - I have 1908, 1911 and 1912. Any others printed? 1909 Nestor Tobacco Baseball "Dope" 1911 Facts for Fans - I have 1911 to 1914. Any others printed? 1917 New York American - James J. Corbett's Baseball Guide
