Computer scientists are trying to shore up broken links in the scholarly literature. Herbert Van de Sompel and Martin Klein were interviewed by the author of this article on the work of the Hiberlink project. They have investigated the extent of reference rot on scholarly domains and their results show an alarming link rot ratio. They have also explored ways to mitigate it through more systematic web archiving practices and link decoration techniques.
