"Other than maybe the iPhone, I can't think of a single invention in the last 15 years I've gotten more rewards from than Lee Sinins' Complete Baseball Encyclopedia. People are always asking me where I come up with my famous Mike & Mike trivia questions. Now it can be told: More of them have come from the Complete Baseball Encyclopedia than from all other sources put together."--Jayson Stark


"It is impossible to adequately follow, cover or enjoy baseball without Lee Sinins' online encyclopedia. The ways I use it cannot be counted."--Peter Gammons


"Lee Sinins' Complete Encyclopedia is best reason yet developed to own a computer. I think I must own a copy of every baseball encyclopedia there is or ever was, and occasionally I find that I still need to pull out one of the others, but not very often; the Complete Baseball Encyclopedia covers 97% of my needs. Whether I'm working or playing, calculating or daydreaming, the Complete Baseball Encyclopedia pops up to help out. I turn it on in the morning; I turn it off when the house is on fire. Otherwise, I'm using it."--Bill James


"The Complete Baseball Encyclopedia is an invaluable affordable research tool that I have used for the last 12 years. The search criteria are vast and intuitive in finding information on any player's batting, pitching and fielding. The ability to create season or career leader lists in any category using multiple criteria is a feature that is not available with more expensive and less extensive tools. This is a quick access must for any serious baseball statistic historian."--Joe Haardt
