It is with great joy and fanfare that we announce the inclusion of Perma citations in the newest version The Bluebook!

Cross-posted from Et Seq., The Harvard Law School Library Blog:

“The 20th Edition of The Bluebook is now available and includes a new rule: 18.2.1(d), which states:

‘Archiving of Internet sources is encouraged, but only when a reliable archival tool is available.  For citations to Internet sources, append the archive URL to the full citation in brackets” – the rule includes the following example:

Letter from Rose M. Oswald Poels, President/CEO, Wis. Bankers Ass’n, to Elizabeth M. Murphy, Sec’y, SEC (Sept. 17, 2013),[]. is also the example used to demonstrate the archived sources rule in the Rule 18.1 Basic Citation Forms for Internet Sources table on page 178:

Rocio Gonzalez, Puerto Rico’s Status Debate Continues as Island Marks 61 Years as a Commonwealth, Huffington Post (July 25, 2013, 9:00 AM),[].'”

A big thank you to everyone at The Bluebook for recognizing the problem of link rot and recommending as a reliable tool for stamping it out!


100 Registrars

The team is pleased to announce that we’ve added the 100th registrar to our perpetual archiving system!

With more courts, libraries, and schools participating everyday, Perma is growing faster than ever.

We’d like to recognize our 8 most active Registrars who are leading the way in archiving: Columbia, University of Texas, William & Mary, Boston College, Vanderbilt, Boston University, Northwestern, and Indiana — thank you for helping to stomp out link rot! at AALL will be at the upcoming American Association of Law Libraries annual meeting in Philadelphia, singing the gospel of perpetual content and rot-proof links.
