American Jurisprudence (second edition is cited as
Am. Jur. 2d) is a legal encyclopedia of the
United States law, published by
West. It was originated by Lawyers Cooperative Publishing, which was subsequently acquired by the
Thomson Corporation. The series is now in its second edition, launched in 1962. It is a staple of
law libraries, and the current edition is over 140 volumes, updated with replacement volumes, annual pocket supplements, and a New Topic Service binder. The discussion has extensive research references to other Thomson West publications, including sister publications
Am. Jur. Trials, Am. Jur. Proof of Facts, Am. Jur. Pleading and Practice Forms, and
Am. Jur. Legal Forms. Before Thomson's acquisition of West Publishing, it was a competitor to
Corpus Juris Secundum.
Am. Jur. is available online through both
Westlaw, and
LexisNexis.
