The landscape of copyright law has changed dramatically since the last edition of Understanding Copyright Law in 2005. During the past several years both the Congress and the courts have tried to adapt copyright law to the new, interactive (internet 2.0) digital technologies, such as YouTube, and Facebook, and to efforts like the Google Book Search Project. This new 6th edition of Understanding Copyright Law has incorporated all the recent case law and legislative developments, focusing on the challenges of the digital age. Written with clarity and precision, this 6th edition of Understanding Copyright Law remains the most accessible and comprehensive text for students of copyright law.
