This book does a tremendous job of providing the historical context behind the importance of the public domain in our tradition of "free culture." It also provides a good historical look at the history of copyright law, and really helps the reader break free of some of the current ways of thinking about copyrights and their importance in fostering (or inhibiting) the development of our culture. The flaws are that it does get repetitive, this is certainly a subject I know well, so that may be some of it, but it does seem to go over the same points repeatedly. Second, it doesn't give quite enough discussion of how the architecture of the internet makes copyright enforcement generally more difficult (in practice). Although the RIAA and the like have started to sue individuals, and are now automating that process, it doesn't really seem they've been effective as the proliferation of illicit content seems rampant, which gets to the third flaw is that it really needs an update, a lot has happened to the Internet since this book was written, and a look at current status would be a big help.
