A number of maps are held in Special Collections & Archives (SCA). Many maps are catalogued and can be found by searching in the Library catalogue for the relevant city. Several appear in fonds maintained by the department including the Grand River Conservation Authority fonds and the Schantz Russell Family fonds.
A selection of SCA's historical maps can be viewed online on the Waterloo Digital Library.
