1. A method, devised by Berners-Lee as part of his World Wide Web software, of embedding omni-directional links within a given digital text (encoded int he form of an HTML document and displayed on a web browser) which connect to other HTML texts without the need for extra navigation.
2. A visionary concept of Ted Nelson (an American new media theorist, b.1937) for a human-computer interface in which computers present a given text from multiple viewpoints, making it a malleable object that can be ’played with’ in order to deepen a person’s understanding.
3. Any text structured in a way that is nonlinear or nonsequential, having no clear beginning, middle, and end, or in which the reader has control over the sequence. Where such texts link to others through hyperlinks, the boundaries of the text may be blurred or the text may be perceived as unbounded. A network of interconnected writings. Consists of discrete units – pages, paragraphs, graphics – and the links between them. A hypertext doesn’t need to have any canonical order. Because every path may define an equally convincing and appropriate reading, the hypertext’s multiplicity (or overdetermination) suggests a changed relationship between the reader and the text.
Hypertext can be described as "a system of accessing textual data, that is accessed sequentially, but the sequence is determined by the end-user rather than by the original author”.
