The reality of hypertext today is rather different. Driven by the needs of particular applications and by platform and market constraints, a plethora of competing and incompatible hypertext systems have arisen. Their user interfaces vary radically, from the fixed frames of KMS to the multiple scrolling texts of Guide. The data models are equally diverse, from the formalisms of HAM and Inter-media to HyperCard’s combination of object structure with procedural links. Many of these systems have already carved out substantial market niches and a growing amount of content is being created within their confines. Indeed, our ability to make global statements of utility for any of these approaches is still quite limited, and there may be no one best way of storing or presenting hypertext which suits all users and applications.
