Expanding the notion of links

Research in the humanities, particularly in text-oriented fields such as Classics and Religious Studies, poses particular challenges to hypertext and hypermedia systems. The complex set of primary and secondary documents form an intricate, highly interconnected network, for the representation of which hypertext is ideal. The variety and quantity of links which are needed pose challenges especially for data structures and for display and navigation tools. The specific needs arise in other contexts as well, particularly those with very large or complicated document collections.
