Munsell's Genealogical Index, as this work is generally known, is an index to family histories "buried" in biographies, periodicals, compendia, newspapers, proceedings, transactions, local, town, and state histories, and, in fact, any work that might yield genealogical information--up to the time of original publication in 1908. Its range is immense, and it is therefore not surprising that it contains over 15,000 family names with upwards of 60,000 references to printed works, giving author, title, and exact pages of the work in which the genealogical data are given.
