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. Now in its third edition, this is the first edition to provide websites and e-mail addresses. Besides its obvious genealogical uses, the County Courthouse Book can also be used for land title searches, legal investigations, questions of property rights and inheritance, and indeed personal searches and investigations of all kinds. But it is the genealogist who stands to benefit most from the book because it offers a concise guide to the county courthouses and courthouse records which are the main focus of his research.
