Medieval Digital Resources (MDR)

MDR is a curated database of peer-reviewed digital materials for the study of the Middle Ages. Users can browse an alphabetical list or search using controlled-vocabulary subject tags to find vetted online resources of many types, including: imagebanks; bibliographies and reference works; pedagogical tools; editions and translations; music and other multimedia collections; interpretative websites; and new works of digital scholarship. Please note that MDR does not include resources that are paywalled or require password access, although some resources may have restrictive use-licenses. The Database can be accessed from the Resources tab of the Medieval Academy of America website.

Resources are selected for MDR by subject and digital specialists with reference to the rigorous Standards for Web Publication developed by the Medieval Academy of America (MAA).

MDR welcomes nominations of resources for inclusion in this growing collection. Please use the Suggest a Resource Form to offer recommendations for inclusion, after first ensuring that the resource is not already part of MDR. For general comments or questions, please email

Several dozen MDR resources have been designated “National History Day Selected Resources” by our team of K-12 educators. These resources – selected for their accessibility and user-friendliness – are identified as such in each resource’s introductory text. You may also retrieve the entire list here by searching for “National History Day” in the “Search Term” box.
