Chapter One Hundred Twenty: I Work at a Public Library

This is a collection of extremely short vignettes (all are less than a page long) that recount hilarious real-life interactions between librarians and the patrons they serve.  Its arrangement into themed chapters, with each chapter assigned the appropriate Dewey number, is cute and fits the mood of the book perfectly.  If you're looking for something to make you chuckle aloud, I Work at a Public Library is a strong contender.
