Contrary to popular belief, matchbooks have no relation to actual books. They are two separate items entirely. A “match book” is a collection of matches, used for starting fires. These should be kept in a safe place, like not next to a stick of dynamite or an arsonist. A “book book”, on the other hand, is a collection of words, which incidentally, can also be used to start fires if you are in an emergency or are a mother who is angry about the information presented in the book.
