"The Bluebook: A Uniform System of Citation,"
by Harvard Law Review (2005).
"Let's be honest. A lot of people felt that Bluebook had fallen off. After that award show confrontation with ALWD and the concealed weapons charges, Bluebook looked like they were on the ropes. That only makes this 18th edition more triumphant for the Bluebook. A stunning return to the form that made them such an irresistible bunch of ragamuffins to begin with, Bluebook has a sure answer to the naysayers who thought they couldn't adapt to the electronic movement--a blistering tribute to Internet citation." - an Amazon reader
"The Redbook: A Manual on Legal Style,"
by Bryan A. Garner, Jeff Newman, Tiger Jackson (West 2006).
The Redbook provides a comprehensive guide to the essential rules of legal writing. Unlike most style or grammar guides, it focuses on the special needs of legal writers, answering a wide spectrum of questions about grammar and style – both rules as well as exceptions. The Redbook also gives detailed, authoritative advice on punctuation, capitalization, spelling, footnotes, and citations, with illustrations in legal context. Designed for law students, law professors, practicing lawyers and judges, the work emphasizes the ways in which legal writing differs from other styles of technical writing. The "how-to" sections deal with editing and proofreading, numbers and symbols, and overall document design.
