Since its first edition in 1972, and especially with the completely revised and greatly expanded 2nd edition in 1990, this comprehensive work has become the standard guide and textbook in the pursuit of U.S. genealogical research. Beginning with the background to research -- what "research" actually means, specialized terminology, basic principles, library fundamentals, and all the rest -- Greenwood teaches you, with great clarity and many examples, how to identify what information you need, how to go about locating it, and how to organize it once you've found it. The second, much larger part of the book, leads the reader through the use, analysis, and interpretation of all the major sorts of documents and records out there: Compiled sources (including a discussion of the nature of compilations), vital records, census returns, wills and probate records (and how to become comfortable with legal terminology), local and federal land records, civil and criminal court records, church records, records relating to immigration, military records, and cemetery and burial records. He discusses the nature of abstracting, clears up common misconceptions about court records, points out the limitations of the census, and presents a largely rewritten discussion of the standards of evidence. When the 2nd edition came out a decade ago, the author thought his book would probably never need another major revision, just minor updates. But that was before the personal computer and Internet revolutions forced him to rethink his position, and this edition includes an entirely new and rather lengthy chapter on the appropriate use of the computer in genealogical research and also on its built-in limitations. He also took the opportunity to add a chapter on the legal issues relating to women's property rights, and (of course) made all those minor corrections and updates he had expected. Bluntly, if you can afford only one how-to book for your home genealogy shelf, get this one.
