Where can I go to look at the Sanborn Fire Insurance Maps?

Several years ago, the Tulsa City County Library donated their Sanborn Maps to the Tulsa Historical Society. The Sanborn Fire Insurance Maps for the city of Tulsa can be viewed at THS. Contact the Tulsa Historical Society at: 2445 S. Peoria, Tulsa OK 74114. Phone: (918)712-9484.
The Tulsa City County Library does have access to digital Sanborn Maps (1867-1970). These are available from home and all TCCL libraries with a valid library card.
