The earliest minutes in this record group for the Committee on Museum begin with its October 7, 1885 meeting. The committee, however, apparently existed prior to that date. In the Board of Trustee minutes pertaining to bylaw amendments presented on January 24, 1882, the "Committee on Museum Collections" comprised one of the standing committees and was "in charge of all objects in the Museum and of their arrangement and exhibition." In amendments presented in April 1885, the committee had the same responsibility, but now was entitled "Committee on the Museum." In 1947 the Committee name changed to "Board of Governors." The minutes continue under that title through November 1964. The minutes for both entities are bound in 13 volumes.
Some correspondence of John S. Jenks, Museum Committee chairman, and of his successor, R. Sturgis Ingersoll, are included in the "Miscellany" series, as are attendance sheets of the Board of Governors during the 1961-1962 and 1962-1963 fiscal years.
