The papers of the State Bank of Commerce span the years 1901 to 1911. They include correspondence and bound financial volumes. In addition to the routine bank correspondence there is also personal correspondence of bank president, B.F. O'Neil, relating to investments and his activities in the Republican Party. Among his frequent correspondents are Governor James H. Brady and William E. Borah. Also included is an early treasurer's book for the town of Wallace, Idaho.

The correspondence is widely scattered, leaving large gaps in the sequence. Several volumes listed on the original inventory were missing at the time of processing. These include one Auxiliary Book, one Trial Balance Book April 1910 to 1911, two Balance Ledgers, 1901-1902 and May 1905 to 1906, one Teller's Cash Book March 1904 to June 1906, and one Closed and Transferred Accounts book. Several volumes not on the original list were with the records, and it is possible the missing volumes were misidentified originally.
