The term hypertext was coined by T.H. Nelson circa 1965 to describe text (later described as being words, pictures and sound) which is not constrained to be linear (i.e. sequential; Kahn et al, 1988; Nelson, 1990). In particular, hypertext can be viewed as text which contains links to other texts. A hypertext document can therefore be thought of as a collection of texts and the links between them which can logically be viewed as a single entity. There is no requirement that the constituent parts of a hypertext document must be stored as a single entity. An anchor within a hypertext document is defined as some collection of text which is the source or destination of a link. Figure 10.1 provides a simplistic view of the construction of a hypertext document.
