For more than a century, Black’s Law Dictionary has been the gold standard for the language of law. Today, Thomson Reuters released the enhanced 10th Edition.

Edited by Bryan A. Garner, the world’s leading legal lexicographer, the 10th Edition is the most authoritative, comprehensive law dictionary ever published. It contains more than 50,000 terms, including 7,500 new ones. In addition, there are more than 16,000 new definitions and expanded bibliographic coverage, with more than twice as many sources quotedBlacks10th and cited than in the 9th Edition. The earliest usage dates in English-language contexts for nearly all terms are also included; Black’s is the only legal dictionary with this feature.

Its namesake comes from its founder Henry Campbell Black who published the first edition in 1891. Today, it is the reference of choice for legal briefs and court opinions as well as being cited as a secondary legal authority in U.S. Supreme Court cases.

Professor Garner took some time to answer a few questions about the significance of the 10th Edition in a special Legal Current podcast, which can be heard by clicking here.

Below are just a few of the new terms that have been added to the 10th Edition:
