The Shamharts researched the location of the post offices, township by township, and published their original findings through a series in the Scioto Voice newspaper ten years before this book was published. They have since updated their research with maps, photos, engravings, and an updated list of postmasters. More than 400 postmasters are listed, along with the years served. This is a valuable resource for this county if you are searching for communities that no longer exist, an ancestor, or are interested in Scioto County’s postal history.
