Jytte Klausen, a professor of politics at Brandeis University, has written a scholarly study of the ructions of 2005-6 when a newspaper in her native Denmark, Jyllands-Posten, pubished twelve cartoons of the Prophet Muhammad. It's called The Cartoons that Shook the World, and it's just been published in the UK by Yale University Press.
Remarkably, the book doesn't contain reproductions of the cartoons or any representation of Muhammad, even those from Ottoman art that the author had originally included. The reason is that Yale University Press declined to publish the book if it contained these illustrations. I wrote about Professor Klausen's case, and its implications for freedom of expression, a little while ago.
I've now reviewed the book for the new issue of Prospect magazine. I'm afraid the link is subscription-only, but - regardless of what you think of the review - the issue of Professor Klausen's treatment is so important that I'll give it anyway. At least the section that can be freely viewed contains my judgement of the book, which is that it's a model of investigation and exposition.
