"The three volumes of this work comprise a wealth of information about persons who lived on the frontier, whether that was the trans-Appalachian frontier, the 'wide Missouri' frontier, the mining regions of the Rockies, or the gold-mining/ranching frontiers of California, Oregon, or Ari-zona."--Booklist. "The index ...adds to the reference value of the book...Highly recommended."--American Reference Books Annual. Stretching from "Aaron, Sam, Arizona pioneer" to "Zutacapan, Acomo pueblo chief," the three-volume Encyclopedia of Frontier Biography profiles approxi-mately 4,500 frontier figures. Volume I (A-F) includes Billy the Kid, Daniel Boone, Calamity Jane, George Custer, Buffalo Bill, Cochise, and John C. Fremont, among others. There are also entries for worthies less well known: Big Nose Kate, Nellie Cashman, Scott Cooley, to cite a few. Even Gary Cooper and other actors who portrayed westerners are sketched in. Thrapp's richly detailed biographies are continued in Volumes II (G-O) and III (P-Z). The Encyclopedia of Frontier Biography is the product of a lifetime of study by Dan L.Thrapp, whose previous books include The Conquest of Apacheria (1967) and Victorio and the Mimbres Apaches (1980).
