The title of the book is pretty straightforward: The Monstrumologist refers to Dr. Warthrop. Since the book is ostensibly a transcription of Will Henry's journals that he wrote to help exorcise his guilt and memories of his service to the doc, it's a pretty fitting name. It's also an eye-grabber. If Yancey had titled the book Will Henry it wouldn't really jump off the shelves the same way, if you know what we mean.
