DMMmaps (Digitized Medieval Manuscripts Maps) is a portal, indicating where in the world libraries have digitized (part of) their medieval manuscripts and have made these available online. It is a crowdsourced project: anoyone who is aware of a digitized library that is not on the maps, can communicate this to the makers of the website and it will be added. In August 2015 almost 400 libraries were included. Each one of these contains digitized medieval manuscripts that can be browsed for free.

There are different ways to view the libraries: through a map, or through a spreadsheet. For each library an indication of the number of digitized medieval manuscripts is provided.

DMMmaps is a project by Giulio Menna and Marjolein de Vos.
