In addition to names and addresses, a city directory may also contain a business directory, government directory, and listings of town officers, schools, societies, churches and post offices. Many local businesses placed advertisements in the directories, which provide fascinating insights into the economic, social and technological trends of the time.
A total of 115 books were scanned, with directories contributed by the Peterborough Public Library, Peterborough Museum and Archives, Trent Valley Archives and Trent University Archives. Funding for the project was provided by the Peterborough Public Library.
