Lexis Source Note: "Comprehensive and authoritative, Weinstein's is cited in an average of half a dozen federal opinions every month, and was cited by the United States Supreme Court in most of its leading evidence decisions over the past decade. The new edition continues the Weinstein's Federal Evidence tradition of providing comprehensive and authoritative analysis of federal evidence law. This edition has improved on the original edition by making its information more accessible in both our electronic and print formats. Chapters are organized by rule number, and the discussion in each chapter is broken down into logical descriptive topical section headings to enable users to quickly find the specific information for which they are looking. The analytical text focuses on the current state of the law and includes footnotes organized by circuits (with brief descriptions of each case), while retaining information on the historical development of the law in historical appendices to each chapter. In addition to clearly setting forth the law, Weinstein's Federal Practice provides expert analysis and coverage of unsettled evidence issues."
