First published in 1891, Black's is now in a 6th edition that reflects changes in tax, finance, commerce, health care, environmental and criminal law. Terms are listed alphabetically with cross-references, and entries give basic legal definitions, word usages, citations, and pronunciation. Entries range in length from one sentence to multiple-pages with subdivisions. Appendices include a copy of the Constitution, a time chart, of Supreme Court membership, and an organizational chart of the federal government. This is not only a standard reference tool for law, but an important supplement to all high school social studies courses. Also available in a 1992 abridged edition.
