This compilation would not have been possible without the input of Dick Clark, Dwayne Isgrig, Kevin Johnson, Larry Lester, Todd Peterson, Brian McKenna, Patrick Rock, Scott Simkus, and David Skinner, all of whom contributed box scores and/or considerable help on many topics.
I have benefited greatly from the expertise and sharp eyes of many researchers. An incomplete list would include Mark Aubrey, John Bowman, Phil Dixon, Nancy Griffith, Howard Henry, John Holway, Jeremy Krock, David Lawrence, César López (of Cubanball.com), Bill Mullins, Rod Nelson, Tito Rondon, John Russell, Geri Strecker, John Thorn, and Fred Worth.
Families of many ballplayers and other figures associated with the Negro leagues provided invaluable information, in particular Ron Hill, Leslie Penn, and the rest of the Pete Hill family; Francisco Morán of the Carlos, Francisco, and Angel Morán family; Mike Nealy and Elizabeth Heath of the Irvin Brooks family; Andre Padrón and Nancy Padrón of the Juan Padrón family; and Dr. McDonald “Mac” Williams of the Alexander M. Williams family.

Much of the research reflected in this database was done at the Duke University and University of North Carolina-Chapel Hill libraries and the Library of Congress, with side trips to the University of Michigan Library, the Kansas City (Mo.) Public Library, the New York Public Library, and the Johnson County (Kans.) Library.
A number of websites, both free and commercial, made this work much more convenient, including ancestry.com, genealogybank.com, fultonhistory.com, newspaperarchive.com, and the genealogical resources of the Mid-Continent Public Library.
Although the statistical and biographical research presented is mainly derived from contemporary sources, the work of previous Negro league historians has provided invaluable guidance and inspiration. Among the most important works in the field are James A. Riley, The Biographical Encyclopedia of the Negro Baseball Leagues (updated edition, 2002); Jorge Figueredo, Cuban Baseball: A Statistical History, 1878-1961, and Who’s Who in Cuban Baseball, 1878-1961 (both 2003); Dick Clark and Larry Lester, eds., The Negro Leagues Book (1994); Phil Dixon, The Negro Baseball Leagues: A Photographic History (1992); and the many books of John Holway.
A special thanks is due to Daniel Hirsch and Kevin Johnson for all their work in correcting my mistakes and preparing the database, and to Mike Lynch of Seamheads.com for his enthusiastic support of the project.
