This subseries contains the minutes of the Governing Council from the merger of the undergraduate organizations in 1928 to the present. In addition, the minutes of some Assembly meetings (meetings of the entire Society membership) are interspersed in the early 1930s. The minutes for many years appear to be incomplete and some years are missing altogether.

The treasurer's documents consist of ledgers, correspondence, and budgets and financial reports. The first ledger, 1925-1939, was an American Whig Society ledger during the period 1925-1928, and then Whig-Clio continued to use it from that point forward.
