Contained within the Atlas of Canada's Reference Map Series, 1961 to 2010, is a back side of the foldable version of the 1995 North America map. The back side of the map has two large tables. The smaller table gives the names of states, provinces and territories in each of Canada, U.S.A., and Mexico, indicating their accepted abbreviation, and giving their two-letter postal short form. The main table is an index to all populated places shown on the map, indicating their country (and the state abbreviation for places in Canada, U.S.A., and Mexico), with a grid-reference to the map on the front side.
