This online edition of a book published by the National Academy of Sciences is an example of its subject matter as it explores the issue of intellectual property in a digital age. The book examines the question of what happens to copyright issues when innumerable numbers of people can download a book (or a song, e.g., through Napster) from one copy on the Web? (Apparently, the National Academy of Sciences is less concerned about this issue than is the book's author.) Chapter titles include "The Origin Of The Digital Dilemma," "Music: Intellectual Property's Canary In The Digital Coal Mine," "Public Access To The Intellectual, Cultural, And Social Record," and "Individual Behavior, Private Use And Fair Use, And The System For Copyright." The text also considers issues in the emerging field of digital copyright and offers conclusions and recommendations vis-a-vis these issues.
