The author outlines the creation of two dataset: The first involves the encoding of data from original bank Reports of Condition and Reports of Earnings, Expenses, and Dividends (i.e., Call Reports) of about 6,500 state- and nationally chartered Federal Reserve member banks in existence between 1929 and 1935. The second involves the collection of bank-structure data, including mergers, acquisitions, and failures, for this same time period.
