2.5.1.2-16 Evaluating Hypertext Links

The user should be able to evaluate the information to which a link refers prior to actually retrieving it.

Additional Information:
The act of deciding whether to access a particular node imposes a cognitive burden that may interfere with other important tasks. In addition, unproductive searches may interfere with the user's responses or result in the user becoming lost in the information structure during time- critical situations. Therefore, some indication of the nature of the target information (e.g., a 'preview') should be provided.
