This page contains subject headings and book titles for monsters. Like magic, monsters is a subject that is difficult to pin down because it is associated with so many other things: fantasy, folklore, myth, religion, even cryptozoology. Therefore you may want to explore additional subject headings. One characteristic of the Library of Congress classification system, which is the system used by Houston Cole Library, is that like is shelved with like. When you find a book that interests you, scan the titles of the books to either side. You might find something else of interest.
