Fifty-two key decisions of the United States Supreme Court which involve freedom of expression are presented in this book. Cases considered range from 1919 to 1971 and deal only with those decisions of the Court which are specifically relevant to the mass media although major emphasis is placed on the 43 major media decisions handed down from the beginning of Chief Justice Earl Warren's years on the Court in 1953. Each case is presented with the opinion of the Court; in some cases concurring and/or dissenting opinions are also included. The cases presented are landmark decisions in the areas of the role of the Supreme Court, prior restraint, postal censorship, control of broadcasting, obscenity, motion picture censorship, libel, right of privacy, trial by newspaper, and trial by television. Also included are 15 selected reprints of articles on these topics from various journals of law and mass communication. A final section contains three articles which discuss the legacy of the Warren Court. Appendixes include amendments to the Constitution, Justices of the Supreme Court, a glossary of legal terms used in this text, a table of cases, and a general index. (SH)
