Bennett supervised the beginning of microfilming by the society. In 1946 Bennett was assigned by the Utah Genealogical Society to approach the officials of record repositories in the Eastern United States for official permission to microfilm their records, in exchange for a microfilm copy of the records they filmed. Another enticement was that the Society would permanently hold "security copies" on film of otherwise irreplaceable documents, should anything happen to the original records. While Ernst Koehler made the microfilms, Bennett traveled from state to state finding people who would allow the society to film their records. Through these efforts records from nine eastern states were microfilmed.
