Here is the abstract:
The related problems of link rot and reference rot are plaguing legal citations, and until now, legal academics have not had an adequate tool to combat these problems. Perma.cc is a free service that allows authors or members of law journals to create permanent citations to online resources. This article argues that we should expand the use of Perma.cc to capture material that would otherwise be inaccessible behind “paywalls” and material that the Bluebook would require authors to cite in print or “as if” in print. These expansions would be relatively simple to implement now and would greatly enhance the utility of legal citations. Finally, this article suggests three areas in which Perma.cc might expand in the future: expanding Perma.cc beyond law schools, using Perma.cc as a legal blog repository, and using Perma.cc to capture images of print-only materials.
