Sir Terry Pratchett's A Blink of the Screen, which is a collection of his shorter works. A fair section at the back is devoted to Discworld, so I'll post it here in Fantasy.

So far? Really good. Some brilliant stories in this collection, and it's clear from the start he has some level of talent. What's also really good, I feel, is each story is introduced by Sir Terry, and he often gives a brief explanation of the inspiration or the history behind it.
