The Genealogy Annual is a comprehensive bibliography of the year's genealogies, handbooks, and source materials. It is divided into three main sections. FAMILY HISTORIES-cites American and international single and multifamily genealogies, listed alphabetically by major surnames included in each book. GUIDES AND HANDBOOKS-includes reference and how-to books for doing research on specific record groups or areas of the U.S. or the world. GENEALOGICAL SOURCES BY STATE-consists of entries for genealogical data, organized alphabetically by state and then by city or county. The Genealogy Annual, the core reference book of published local histories and genealogies, makes finding the latest information easy. Because the information is compiled annually, it is always up to date. No other book offers as many citations as The Genealogy Annual; all works are included. You can be assured that fees were not required to be listed.
