State by state, county by county, city by city, the Guide to Naturalization Records identifies all repositories of naturalization records, systematically indicating the types of records held, their dates of coverage, and the location of original and microfilm records. The Guide also pinpoints the whereabouts of federal court records in all National Archives facilities, and identifies every single piece of information on naturalizations that is available on microfilm through the National Archives or the Family History Library System, including the call numbers used by each institution.

"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.

A two volume set which provides researchers with more than 70,000 links to every conceivable genealogical resource on the Internet.
