"The County Courthouse Book is a concise guide to county courthouses and courthouse records. It is an important book because the genealogical researcher needs a reliable guide to American county courthouses, the main repositories of county records. To proceed in his investigations, the researcher needs current addresses and phone numbers, information about the coverage and availability of key courthouse records such as probate, land, naturalization, and vital records, and timely advice on the whole range of services available at the courthouse. Where available he will also need listings of current websites and e-mail addresses." -- Publisher website.
