Rather than focus on "who" makes the determination about students' access to sexually explicit expression, this volume examines the legal issues affecting "whether" to permit that access and "how much" access to allow. In sum, this book is intended to facilitate meaningful discussion about the regulation of minors' access to sexually explicit material and the role of educational institutions and individual teachers and librarians in controlling such access. After "Introduction," the chapters include: (1) "The Internet and Sexually Explicit Expression" (The Internet in Classrooms and Libraries, Sexually Explicit Expression on the Internet, Notes); (2) "Legal Issues and the Internet" (Application of the First Amendment, Intellectual Property, Economic Issues, Privacy, Security, and Encryption, Multinational Impact and Regulation, Notes); (3) "The First Amendment and Sexually Explicit Expression" (Introduction to the First Amendment, Obscenity, Material that Is Harmful to Minors and Variable Obscenity, Children, Technology, and Indecency, Communications Decency Act, Notes); (4) "Controlling Sexually Explicit Expression on the Internet" (Legal Regulation, Controlling Access, Notes); (5) "The Value of Internet Expression" (Adults and Expression on the Internet, The Value of Unrestrained Expression for Children, Notes). (Contains sources for further research: cases, secondary materials, online resources, and 49 references.) (AA)
