Abstract
In most hypertext applications there will be occasions where the user knows the location of the information being sought because that location has been visited regularly in the past. This directed navigation can be distinguished from exploratory navigation where the user cannot specify precisely where the information might be within the hypertext system. Directed navigation can be facilitated by providing a personal browser which lists and gives direct access to frequently visited locations selected by the user. Different ways in which this could be implemented are discussed including facilities for automating the addition of new buttons to the personal browser. An appendix provides the code needed to program a demonstration within HyperCard. This monitors the number of times each card in the stack is visited and asks whether a button should be added after a card has been visited some criterion number of times.
