A Stroke of the Pen by Terry Pratchett

A collection of Sir Pterry's -- well, I don't suppose you can call them juvenilia, since he was an adult at the time of the writing, but certainly his early work.

Later than those in the first two collections, and only discovered by accident, when someone realized that stories under a certain byline were very similar to Pratchett's work, and someone else pointed out that the byline's last name was his mother's maiden name.

Short, whimsical stories set in a variety of settings.
