NY Times: Bits Debate: Copyright:

Throughout the debate this week on copyright issues, the question of fair use has come up repeatedly. On Wednesday, the topic for Rick Cotton, the general Counsel of NBC Universal, and Tim Wu, the Columbia law professor, was the legal concept of fair use: how much of a copyrighted work can be included in a review or other sort of work. But in many of the comments we received all week, readers have asked about their own broader sense that when they buy a CD or movie, they purchase rights that include making copies for their personal use.
