"The American Imprints Inventory, a record of imprints from early American books, pamphlets, and broadsides, began operating as a Historical Records Survey project in 1937. It was directed by Douglas C. McMurtrie at the Chicago HRS office. Two products were expected: a file or union catalog of title slips representing the holdings of American libraries and a series of published checklists of state or city imprints within specific time periods. It was agreed in 1938 that the file eventually would come to the Library of Congress. Approximately fifteen million typed slips had been accumulated by March 1942 when work ceased and ownership of the file was formally transferred to the Library." -- "American Imprints Inventory."
