If you’re interested in “authoritative guidance to reasonable questions on subjects covered by the Bluebook,” visit Blue Tips at the Bluebook’s web site. There, Bluebook editors answer common questions and provide helpful advice on a wide range of citation issues. You can submit your own questions as well. If the editors find the answer to your question “useful to Bluebookers generally, it may be formulated into a new tip,” which would appear on the Blue Tips page. Thanks to Amy Burchfield at the CM Law Library Blog (Cleveland-Marshall College of Law) for the tip.
