It's important to provide information on what maps you are looking at so others can locate and view them. For the European Geography topographic map exercise you will need to cite a map in a topographic series. A useful online resource for how to cite maps is http://libguides.mcmaster.ca/Cite-Maps.
The Documents Reference Collection (first floor Knight Library) in the study area near the map collection has Cartographic citations : a style guide (Call number Z6021. C55 2010) if you want further details on how to cite maps.
