In the section on critiques should be added Alex Beam's more-general critique of Adler and the GBWW project:
A Great Idea at the Time: The Rise, Fall, and Curious Afterlife of the Great Books.
It is good for a giggle and uses the rhetorical technique of lampooning the other's (Adler's) over-seriousness; although I thought that Beam's pen-nib was a bit too sharp, and I ended up both pitying Adler and cheering him on more than expected.
Worth borrowing from your local library, but probably not worth spending money or valuable shelf space on it.
