To establish connections between medieval manuscripts in the nineteen-eighties without visiting the holding institution, researchers were dependent on printed catalogues, the secondary literature and facsimiles and microform reproductions. This paper reviews the changes that the Internet has made to the way research is conducted in this area. Only the abstract of J. Pearce’s article is online, but web links are given. The web site „Our medieval heritage“ (2002) provides abstracts of articles as well as adjunct visual material in the form of photographs, maps, diagrams and web links for a series of articles published as a festschrift for John Tillotson. Another article „Multimedia Medievalia: The Fate of Traditional Scholarship in a Post-Modern World“ sounds also interesting.
