Book excerpt: This is the essential how-to manual for anyone interested in baseball research. How to Do Baseball Research updates and greatly expands The Baseball Research Handbook, published by the Society for American Baseball Research (SABR) in 1987. A group of talented SABR members provide information and advice in a variety of areas, including how to use libraries and archives, find illustrations, and prepare manuscripts for publication. Particularly noteworthy is the new information on using the computer for baseball research and statistical analysis. Contributions from SABR committee chairs and longtime SABR researchers add valuable specifics to the fundamental advice in the ten chapters.
