Mary Appelhof's book is both amusing and educational. This is the "Vermi Bible" for most people who compost their household waste with worms (vermicomposting).
This 2nd edition includes description and discussion on commercially-available vermicomposting bins. Unfortunately, with the excitement and growing interest in worm composting, there are bins now available that are not reviewed in the book. (I guess we'll need a 3rd Edition!)
For the beginner as well as the worm hobbyist, I recommend this book highly.
