This is a collection of 114 Missouri County plat books published by W.W. Hixson & Co. Although the exact year of publication is unclear, it is estimated to be late 20's to early 30's. The plat books in this collection are held in the Special Collections Departments at Ellis Library at the University of Missouri-Columbia and the St. Louis Public Library. These plat books are quite frequently consulted. In an effort to preserve and make them more accessible, they have been made available online for the public-at-large.
