A complete microfilm set of the minutes from the first meeting of March 20, 1900. There is an index to the minutes filmed at the beginning of each year starting with 1911. However, there is an exception for years 1978-1986 which appear on a separate reel of microfilm (BCA 5175). Information in the minutes is amplified in the attachments, the Board of Estimates files (series 3), and the cassette tapes of meetings (series 2). For some years the attachments have been filmed with the minutes; when they are not included with the film the attachments can be seen with the manuscript minutes in the comptroller's office. Agendas summarizing the items to be covered are in series 4.
