About this guide

This guide is based on The Bluebook. For more details and examples, consult The Bluebook: A Uniform System of Citation (19th ed.) 2010. (REF KF 245 U55  2010).

  • Note, however, that the APA style incorporates various changes into the Bluebook style.
  • The Bluebook style is not used to cite legal periodical articles or books. Use the regular APA style.
  • To cite legal materials from states other than Massachusetts, follow the forms given below for Massachusetts, but substitute the abbreviations found on pages 170-228 of the Bluebook.
  • Some Web-based databases do not include the data required to cite according to these rules. Lexis-Nexis is the best source.
