These remarkable plat books were originally published by W.W. Hixson & Company in the late 1920s and early 1930s. They present a unique view of Missouri during this period of history, and they will be of great interest to historians, geographers, and others. Visitors to the site will find it quite easy to use these plat books, which can be consulted by their county name. The documents are replete with details about lot size, building improvements, street patterns, and so on. The detail and high quality of these images makes this collection a great find.
