One of the great places on the baseball-related internet is the Baseball Biography Project run by SABR (the Society of American Baseball Research). It is exactly what it says it is: a project to put up biographies of baseball figures. Most of them are short-but-sweet, but some are longer, more in-depth

They range from the obvious (Babe Ruth and Willie Mays) to the famous-because-they-are-obscure (Eddie Gaedel and Moonlight Graham) to the downright I-haven’t-ever-heard-of-them obscure (picking randomly: Tom Hernon and Pat Purtell).
A good way to waste time while soaking up some sweet baseball knowledge.
