Enluminures : base de données. It's a free database with more than 80.000 images, as labels and digitalized, reproductions of many illuminations and more than 4000 medieval manuscripts of elements of decoration. This on-line database makes a search through hundreds of municipal French libraries. But if you aren't in the mood to try your French, go to the virtual exhibitions session. (via MetaFilter)
