This collection contains materials related to the Boston Police Department (BPD), compiled by Boston Police sergeant Edward J. Fitzgerald. The bulk of material is a bound set of General Orders issued by the Office of the Police Commissioner, spanning November 1918 to December 1919. The Boston police went on strike in September 1919, and the General Orders contain a combination of policies, procedures, and internal communications covered during the strike period, such as punishments levied against officers who attempted to unionize, and records of patrolmen hired as replacements. The collection also consists of clippings about specific cases, laws, and obituaries, a political committee pamphlet, police union newsletters, instructional manuals for the police examination and the Boston Retirement System, and motor vehicle rules and regulations.
