In the Photography section of the Resource Warehouse you'll find many images that can be used in teaching codicology (the study of the book), paleography (the study of ancient handwriting), and many aspects of medieval culture, with special reference to private devotion and the liturgy.
These images include: illustrations for particular feasts; sample pages from medieval calendars; manuscript decorative elements; details of codicological features, etc.
If you don't see what you need for your teaching or research, let us know--we may have relevant images in stock (100s are available).
