Census records and name lists for New York are found mostly at the county level, which is why this work shows precisely which census records or census substitutes exist for each of New York's sixty-two counties and where they can be found. In addition to the numerous statewide official censuses taken by New York, this work contains references to census substitutes and name lists for time periods in which the state did not take an official census. It also shows the location of copies of federal census records and provides county boundary maps and numerous state census facsimiles and extraction forms.

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. ""
