The Researcher's Guide to American Genealogy;

In every field of study there is one book that rises above the rest in stature and authority and becomes the standard work in the field. In genealogy that book is Val Greenwood's Researcher's Guide to American Genealogy. Arguably the best book ever written on American genealogy, it is the text of choice in colleges and universities or wherever courses in American genealogy are taught. Of the dozens of textbooks, manuals, and how-to books that have appeared over the past twenty-five years, it is the one book that is consistently praised for setting a standard of excellence. The Researcher's Guide has become a classic. While it instructs the researcher in the timeless principles of genealogical research, it also identifies the various classes of records employed in that research, groups them in convenient tables and charts, gives their location, explains their uses, and evaluates each of them in the context of the research process. Designed to answer practically all the researcher's needs, it is both a textbook and an all-purpose reference book. And it is this singular combination that makes The Researcher's Guide the book of choice in any genealogical investigation.
