Here is an essential guide to the formation and historical highlights of 100 Tennessee counties in existence at the time of the work's original publication in 1923. Each essay gives the county's date of formation, the names of all parent counties, the names of some of its earliest pioneers and landowners, the dates its courts were organized, locations of county seats, and additional information on each county's topography and economy.

Snyder County was carved out of the southern portion of Union County in 1855. Named after Selinsgrove resident and Pennsylvanias only three-term governor Simon Snyder (18081817), the county is unique in many ways. It is part of the extensive early-nineteenth-century Pennsylvania Canal Systems Susquehanna Division and home to one of the nations first coeducational colleges, Susquehanna University. In the western section of the county, McClure is a town that was created by and for the convenience of the mid-nineteenth-century Middle Creek Valley Railroad. Snyder County is a historical tour of these ever-changing communities through more than two hundred new and far-ranging images, many never before published, mainly from the outstanding postcard collection of county resident Ron Nornhold.
