Terry Pratchett deserves more critical attention, but he has three strikes against him -- he's popular, he's funny, and he writes fantasy. This collection is a welcome first step towards correcting this neglect. The essays are all quite good. As a librarian, I particularly enjoyed Andy Sawyer's "The Librarian and His Domain". Andrew Butler's essay on "Theories of Humour" places Pratchett squarely in the comedic tradition of Rabelais. John Clute and Cherith Balrdy provide background on the less-familiar children's books, which are harder to obtain here in the US. The other essays are uniformly solid and thought-provoking; my borrowed copy is full of post-it flags.
