Ohio wills and estates to 1850: an index is the culmination of a ten-year project to provide a comprehensive index to the probate records in Ohio. Probate Court was formed in 1852, taking over those functions of the Common Pleas Court which had previously been handled by that office. In most Ohio counties, the records were transferred to the new court, but in a few counties the original probate matters have remained in the Common Pleas Court records.

Genealogists and other historical researchers have valued the first two editions of this work, often referred to as the genealogist's bible."" The new edition continues that tradition. Intended as a handbook and a guide to selecting, locating, and using appropriate primary and secondary resources, The Source also functions as an instructional tool for novice genealogists and a refresher course for experienced researchers. More than 30 experts in this field--genealogists, historians, librarians, and archivists--prepared the 20 signed chapters, which are well written, easy to read, and include many helpful hints for getting the most out of whatever information is acquired. Each chapter ends with an extensive bibliography and is further enriched by tables, black-and-white illustrations, and examples of documents. Eight appendixes include the expected contact information for groups and institutions that persons studying genealogy and history need to find. ""
