This book compiles information readily available for free. This book is not for beginning genealogists. An advanced genealogist will already have attained the details this book provides. SAVE YOUR Money and spend it on "The Everything Family Tree Book" by William G. Hartley or some other suitable reference manual.
I have long been interested in taking the Accredited Genealogist Exam, but have been frustrated with the lack of specific material showing me how to do that. This fills that narrow niche. It has inspired me to prepare more fully for that exam.
This reference guide is recommended for those who wish to take the accreditation examination offered by the Family History Library in Salt Lake City. It is also recommended for others who are doing professional research.
