Manuscript proceedings of the meetings of the Board of Aldermen. In addition to the regular meetings there are also minutes of numerous special meetings and at least some joint meetings were held. Also included in the proceedings are manuscript copies of letters, reports, and other communications received by the Board. One volume includes minutes of a single executive/secret session in 1852. There is, of course, a gap in the records from 1862-1866 during the suspension of Council activities.

The records through 1862 are available on 3 rolls of 35mm microfilm; volumes 11 and 12 of the minutes and proceedings are unfilmed and only available in original format.
