General Introduction The purpose of these brief introductory remarks is to tell you, first, what kind of information you can find on this website and, second, how you can retrieve this information. The core of the whole site is a scholarly database. This database contains all kinds of information about the illuminated medieval manuscripts of the Koninklijke Bibliotheek and the Museum Meermanno-Westreenianum. You can get access to this 'electronic catalogue' in various ways. When choosing your way, your own expertise and wishes should guide you. If you do not routinely consult databases and your interest in medieval illumination is not a professional one, you may start with our guided tour.
