Accounts Payable Vouchers - Group I, 1892-1919

Subseries 1, Accounts Payable and Memorandum Vouchers, 1892-1929, contains one continuous run of more than 18,000 vouchers dating from the time the system was implemented in 1892 until Frick's death in 1919. Vouchers are numbered sequentially, but start over at 1 after reaching 10,010 in 1909. Eleven indexes, in which payees are listed alphabetically beginning in 1901, are filed at the beginning of the subseries. The original index covering the years 1892-1900 does not survive with these papers, but an electronic index for that period has been compiled. See the archives staff for more information.
