Link rot in the law. Causes and remedies – Real Lawyers:
How bad is link rot?
A 2014 Harvard Law School study study by Jonathan Zittrain, Kendra Albert and Lawrence Lessig, determined that approximately 50% of the URLs in U.S. Supreme Court opinions no longer link to the original information. They also found that in a selection of legal journals published between 1999 and 2011, more than 70% of the links no longer functioned as intended.
Any number of things cause link rot.
Eye-Opening for me. Link-rot is something I deal with daily on this blog and in my bookmarks or saved pages. When you have legal cases referencing URLs that are dead, that’s scary.
