Essays are arranged chronologically within each thematic area and provide the historical and social context, as well as the case's legal significance. Each essay begins with "the case in brief," which outlines the date, location, court, principal participants, and significance of the case. The essays vary in length from 1,000 words for "lesser" cases to 2,000 words for cases of "medium-level significance" and 5,000 words for cases of "monumental importance." Each concludes with a brief bibliography. Following the entries are an index of cases and a subject and name index.
This edition contains 43 new essays, half treating cases decided since the publication of the first edition in 1992 and half analyzing older cases. United States v. Microsoft Corporation, Bush v. Gore, and Clinton v. Jones are among the topics of new essays. Most of the essays included in the first edition have been updated by the authors. Format changes in the second edition make it more readable, and the new "Case in Brief" feature offers the user a quick overview. Students and researchers in political science and history, as well as law, will find the encyclopedia useful, and it is recommended for public, academic, and law school libraries.
