404 not found: A study of hyperlinks on Irish academic library websites

Link rot refers to inaccessibility of resources on the World Wide Web due to decayed links. Using a link checking tool the authors examined links from ten Irish academic library websites using the LibGuides content management system. Four percent of links were affected by link rot, rendering them inaccessible. It is recommended that librarians be mindful of link rot when creating content and periodically check their webpages for broken links.
