A new edition of the Bluebook: A Uniform System of Citation will be released next month. According to Hein,
the 19th edition retains the same basic approach to legal citation established by its predecessors. The layout has been updated to make information easier to access. Some citation forms have been expanded, elaborated upon, or modified from previous editions to reflect the ever-expanding range of authorities used in legal writing and to respond to suggestions from the legal community.
Copies are available from Hein for $32.
