The Indigo BookThe Indigo Book is a free, Creative Commons-dedicated implementation of The Bluebook’s Uniform System of Citation. The Indigo Book was compiled by a team of students at the New York University School of Law, working under the direction of Professor Christopher Jon Sprigman.
The Indigo Book isn’t the same as The Bluebook, but it does implement the same Uniform System of Citation that The Bluebook does. The scope of The Indigo Book’s coverage is roughly equivalent to The Bluebook’s “Bluepages”—that is, The Indigo Book covers legal citation for U.S. legal materials, as well as books, periodicals, and Internet and other electronic resources. In addition, The Indigo Book offers citation guidance that is deeper than The Bluebook’s Bluepages—for example, The Indigo Book has citation guidance for bills, and for legislative history, that the Bluepages lack. For the materials that it covers, anyone using The Indigo Book will produce briefs, memoranda, law review articles, and other legal documents with citations that are compatible with the Uniform System of Citation.
