I am glad to see that this Edition of the Bluebook is addressing the problem of link rot by using Perma.cc. I’ve blogged previously about Perma.cc. I used it exclusively on this blog for a time until more than one posts were lost because the link no longer worked. Perma.cc is still the best tool available now to address link rot. Let’s hope that it works out its reliability problems. -CCE
