The Medieval Elbe is a Drupal 7 site. It was developed for History professors Lisa Wolverton and Jonathan Lyon who are developing and presenting research and teaching materials about the interactions between Slavs and Germans in the Central Middle Ages along the Elbe river and beyond. The site allows the professors to highlight the texts and tag them with various labels. This is then presented to users to interact and review texts under those labels. The site is hosted on Drupal Central Hosting.
