Dr. Ernest Drake's Dragonology Handbook : a practical course in dragons (by Dugald A. Steer)

Apparently there are plenty of children out there who are obsessed with dragons; enough, anyway, to warrant a sequel. And that's exactly who this book is for. Any child who is not fanatical about dragons will find it boring in the extreme, but for the right children it will provide hours of fascinating fun as they labor to translate passages written in dragon script, figure out riddles, and follow instructions for improving their skills.

The book is gorgeous -- extensively illustrated and showing great attention to detail in its attempt to look like an antique textbook -- though there are places where ornate fonts on top of pictures are hard to read. The one section children will find disappointing is the chapter titled "How to Draw Dragons," which is badly misnamed and offers no drawing instruction at all.
