Great news from the Perma.cc mailing list!
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), http://www.sec.gov/comments/s7-03-13/s70313-178.pdf [http://perma.cc/B7Z7D9DJ].
Perma.cc 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), http://www.huffingtonpost.com/2013/07/25/puerto-rico-status-debate_n_3651755.html [http://perma.cc/C6UP-96HN].
Our deepest thank you to the editors of The Bluebook for recognizing Perma.cc as a reliable tool for preserving internet sources, and thanks to all of you, our partners, for your continued support!
