Genealogy as Pastime and Profession. Second Edition
Donald Lines Jacobus
Clearly written, this describes the principles of genealogical research, the evaluation of evidence, and the relationship of genealogy to chronology, eugenics, and the law. It covers early nomenclature, Royal ancestry, the use of source material, and the methods of compiling and publishing a family history, and it also deals with characteristic blunders and misconceptions. It is the very foundation of scientific American genealogy.
