Mediaevum.de is a German-language Internet portal for students of medieval German language and literature, providing annotated listings of many important or otherwise useful sites in this discipline (plus others that are at least partly outside the discipline but nonetheless useful for students of it). There is an English-language version of the main page, but this is only infrequently updated. Users unfamiliar with this site might begin by clicking on the Sitemap, which offers links to subordinate pages in readily visible categories. (Updates vary)
This permalink is a direct, persistent URL to the database that will always work and won't break.
