Oregon County Missouri Deed Abstracts 1845-1868 by Nona Williams was published by Heritage Books, Inc. in 1994. It contains 326 pages and two indexes, one is by locality and the other is by surname. It includes abstracts from the deed records from Deed Book 1, 2, 3 and Deed Book A.

This book is out of print, but I recently purchased a used copy. It has a couple of notations in the margins but is otherwise is very good condition.

Sorry, out-of-print
