In the recent issue of the CAUT Bulletin, 56(7), there is a book review by Donald Savage (p. A7-8) of "For the Common Good: Principles of American Academic Freedom". In Savage's words, Finkin & Post's book is a "lucid and concise account of the evolution of the idea and practice of academic freedom in the United States over the last century".
Another review of this book, by Chibli Mallet, entitled "How Did Academic Freedom Make U.S. Universities the Best in the World?", was published in Campus Watch.
I plan to buy the book, $21.78 for Finkin & Post at Chapters.ca, and may even add my two cents on its contents.
