Oxford University Standard for Citation of Legal Authorities (OSCOLA)
From the webpage:
The Oxford University Standard for Citation of Legal Authorities is designed to facilitate accurate citation of authorities, legislation, and other legal materials. It is widely used in law schools and by journal and book publishers in the UK and beyond. OSCOLA is edited by the Oxford Law Faculty, in consultation with the OSCOLA Editorial Advisory Board*. OSCOLA was shortlisted for the Halsbury Legal Awards, 2013 Award for Academic Contribution.
OSCOLA (4th edn, Hart Publishers) is available for free in PDF and the webpage lists supplemental materials, such as OSCOLA styles for popular software packages.
I saw this in a tweet by Carl Malamud who asks:
A sense of public purpose. What happened to Harvard?
As of today, Sales Rank Express (Aaron Shepard) reports that:
The Bluebook: A Uniform System of Citation has a sales rank of 9147.
Grapes of Wrath, Amazon sales rank of 2437.
Snow Crash comes in at 3047.
The Firm, by John Grisham is now ranked at 18619.
Projecting from Amazon sales ranking is uncertain but I suspect The Bluebook is making less money than Grapes of Wrath and Snow Crash but more money than The Firm by John Grisham.
The answer to what happened to Harvard is money.
