The increasingly important issue of secondary liability is represented by decisions in the Ninth Circuit and other courts subsequent to the Supreme Court's decision in MGM Studios, Inc. v. Grokster, Ltd. The book has similarly amplified the caselaw on the limited liability of internet service providers. The Digital Millennium Copyright Act's provisions on technological protection measures and copyright management information are also covered, through well-selected cases and analysis of successive Copyright Office Rulemakings. A revised and updated chapter on fair use traces the expansion of that doctrine in both the digital and the more traditional contexts.

Other expanded topics include the evolving caselaw on copyright ownership and termination of transfers, the increasingly contentious policy issues underlying copyright formalities and the related problem of "orphan works," contractual limitations on user prerogatives, and international issues. There will also be more photographs illustrating current cases dealing with originality and infringement. The casebook will continue its position as the outstanding book in the field-comprehensive and thorough, and stimulating and enjoyable for both teacher and students.
