The profession owes a great debt to the compiler and editor of this monumental resource for genealogy and local history research, originally published by Netti Schreiner-Yantis. The new fifth edition of this indispensable set, now the most important current bibliographical reference tool in the field, has been greatly expanded and updated. The Family History Volume is divided into two parts, family histories and compiled genealogies, and contains nearly 5000 entries. The index also includes family names from the compiled genealogies, a useful feature for libraries that own these compendiums. The General Reference & World Resources Volume is arranged by two broad topics. "General Reference" includes adoption, census, church records, immigration, military, religious and ethnic groups, and many other useful categories. "World Resources" is arranged alphabetically by country, from Australia to the West Indies; the section for Great Britain is particularly rich. The two-part U.S. Sources & Resources Volume provides regional and state coverage, beginning with the five major regions of the United States and concluding with an alphabetical state list. This volume, like the others, provides a numerical and alphabetical list of vendors at the front. The set as a whole should be one of the first places a researcher looks to determine if a genealogy on his or her family has been published; to identify books for sale; and for a comprehensive, current bibliography. Highly recommended for all libraries.Judith P. Reid, Library of Congress, Washington, D.C.
