Researching Legal Ethics & Professional Responsibility

This research guide provides an overview of research sources on legal ethics and professional responsibility.


A legal treatise is a book or set of books on a legal topic that are written by experts.  Sometimes students get confused between "treatise" and "treaty."   A treatise is a scholarly book or set of books about a legal topic.  It is a secondary source. A treaty is a primary source legal agreement between countries. A good treatise is thorough, explaining and even critiquing, the law.  A treatise can be an extremely useful secondary source for research because it gathers such detailed information on a particular legal topic or issue into one publication. 

You can find legal ethics treatises for specific practice areas and specific jurisdictions, as well as general treatises.

Many treatises are updated by pocket parts or supplements.  Some treatises, known as "loose-leafs" are updated by new pages being inserted into a binder.

Rule 15 of The Bluebook (21st ed. 2020) covers citing treatises. There are many variables in citing a treatise so definitely consult the rule for its many permutations. 


Generally, a citation to a treatise should contain the following elements:

  • Volume (if applicable)
  • Author (large & small cap font) (see R. 15(b) for more than 2 authors and R. 15(c) for institutional authors)
  • Title (large & small cap font)
  • Section and/or Page
  • Editor, translators (if applicable)
  • Edition
  • Copyright Date

If you have an institutional author, abbreviate (use Tables 6 & 10) only if it is unambiguous. Do abbreviate United States.
