From the website: "The following is a list of 25 map clusters one might consider essential for teaching German history for the period 1870 to 1945. They are ordered roughly chronologically, as outlined in the table of contents, and conform loosely to the topics, such as "Imperial Germany," in the navigation bar above. The bar brings you directly to the topics.

I briefly describe the map, or map cluster, and (where possible) offer a link to a high resolution version of it. These links also provide more information about the map itself, unless, of course, I made the map using arcgis (HWS Map) or the map is from my own map collection (HWS Collection). The emphasis in this list is on publicly available, high-resolution images, with a mix of period and modern maps."
