Generally, in mathematical publishing, when someone refers to a book by the author's name, the title is (essentially) the topic.

Without clicking the link, I'd bet dollars to donuts the book is titled "Hinged Dissections", "Hinged Dissections: A Pivotal Analysis", "Hinged Dissections: Swing Sets", etc.

edit: it's "Hinged Dissections: Swinging and Twisting". I prefer "A Pivotal Analysis".
