Secondary Legal Sources may restate the law, but they also discuss, analyze, describe, explain, or critique it as well. These include reference works such as dictionaries and encyclopedias, books, treatises, theses and dissertations, journal articles, loose-leaf publications, indexes and abstracts.
Treatises, not to be confused with treaties, are book-length expositions on the law as it pertains to a particular subject. Treatises may be scholarly in nature, such as Murray on Contracts, or they may be geared toward a legal practitioner, such as a manual or handbook.
