The Winnipeg Henderson's Directories from 1880 to 1965 can be found here. Henderson's Directories are directories of households and businesses. They were compiled by individuals who went door to door, gathering information about the citizens and businesses in a city. Chamber of Commerce information, such as the demographics of a city, was also usually included. Henderson Directories thus provide a comprehensive (but not complete - it was possible to not have your information included) directory of the buildings and people in a city.
