New Study on Link Rot in Supreme Court Opinions

A recent New York Times article has highlighted a topic that has been of recent interest to law libraries and legal scholars: link rot in legal citations.  The article addresses a forthcoming study by Jonathan Zittrain, a professor of Law and Computer Science at Harvard, Larry Lessig, a professor of Law and Leadership at Harvard, and Kendra Albert, a Harvard law student.  The study looks specifically at link rot in U.S. Supreme Court opinions, finding that nearly 50% of the links in Supreme Court opinions no longer work.  The study also looked at link rot in law journals, including the Harvard Law Review.  Professor Zittrain discusses the study in a recent post on his blog and provides a link to the study on SSRN. 

Law libraries, who have long had an interest in this topic (see a recent article here by law librarians Raizel Liebler and June Liebert in the Yale Journal of Law and Technology), are becoming more involved than ever in addressing link rot in legal citations.  Zittrain's blog discusses a new project called Perma.cc, which is a project undertaken by the Harvard Library Innovation Lab and a number of academic law libraries.  According to Zittrain, the project "will allow those libraries on direction of authors and journal editors to store permanent caches of otherwise ephemeral links."

(As an aside, the New York Times article mentions the recent book by Richard A. Posner titled "Reflections on Judging."  The Law Library has recently received this book as part of its collection.  See the library's catalog for more information.)
