"The Online Resource Book for Medieval Studies (ORB) is a cooperative effort on the part of scholars across the internet to
establish an online textbook source for medieval studies on the World-Wide Web. [...] The Library page lists primary sources, many in translation. The Graphics page will provide links to scanned images available for downloading. The Reference Shelf contains a melange of useful tables, timelines, and discussions of technical matters. The Connections page provides links to other useful collections, the homepages of medieval scholars, and other relevant pages on the Internet. Links to existing resources are also provided in essays or contents pages where their presence is deemed helpful and convenient for the reader."
