Required Reading: Classic resources you shouldn't research without.

Whether you're newbie or a seasoned genealogist, you'll find helpful information and guidance within the 676 pages of The Researcher's Guide to American Genealogy, 3rd edition, by Val D. Greenwood (Genealogical Publishing Co.). First released more than 25 years ago, it's still considered the standard reference for US roots tracers - in fact, it's often used as a textbook in college and other genealogy courses. Part 1 explains the methods of genealogical research and analysis; Part 2 delves into specific sources. Though some of this seven-year-old edition's details are dated, Greenwood's clear, concise writing and comprehensive coverage will teach you timeless principles of sound genealogical research.
