Unique Anchors

Throughout this course anchors are used in different ways. When it is meaningful a word or phrase is used that gives some information about the destination. A link pointing to a node about World Wide Web is usually indicated as such. The destination of the link however is not always the same. The following phrase: World Wide Web also looks like an anchor, but it points to a different node. Also, when there is additional information about something, like World Wide Web it is not uncommon to write that the additional information is here.

Some systems, like Hyperties, forbid the use of a single word, like here, to be used to point to different nodes, depending on where they occur. This unique anchors feature avoids confusion when the user clicks on the same word in different places and is taken to different destinations.
