Multiple access paths to the same information with a method in place to check the validity of site-wide links.
Multiple links to the same page increase discovery success, allowing the same information to be repackaged for presentation to different viewing audiences. Restraint, however, is exercised. Gratuitous links can undermine hierarchy and structure. Different labels (or "anchors") for the same page can be misleading. While different labels are sometimes a natural consequence of the context in which the reference to a page is made, it can mislead the viewing audience to follow a previously visited link (even if the software/browser being used indicates previously visited links).
The accuracy of links is determined by vigilance, feedback from the viewing audience, and site-scanning software. Invalid links undermine credibility, which can only be restored by timely repairs to such links.
