Considers the frustration and annoyance experienced by World Wide Web users when encountering dead links which have occurred due to "link mortality". Points to recent research in which 2,471 articles and 4,224 URL references appearing in the period, 1995-1999, were studied and where it was found that almost 50% of the references had become inaccessible within four years of the publication date. Investigates the phenomenon of link mortality to determine the various causes and offers advice to Webmasters in reducing the incidence of dead links. Concludes with a discussion of the important potential role of OpenURL, Digital Object Identifier (DOI), LOCKSS (Lots of Copies Keeps Stuff Safe) and the Internet Archive in helping with this problem, noting that there are many difficult problems which remain to be solved by methods other than the existing, simple solutions.
