The significance of linking
The link has been central to the idea of hypertext since its inception and continues to enjoy widespread popularity. This paper briefly explores the history of links and draws a distinction between navigation and retrieval in information handling. The value of information content in certain navigation and retrieval tasks is examined and the challenges of extending content-based retrieval and navigation to non-text media are identified. Finally, the goal of more versatile content- and concept-based navigation is discussed.
