Wiki säger

In books and other works, a subtitle is an explanatory or alternate title. For example, Mary Shelley used a subtitle to give her most famous novel, Frankenstein; or, the Modern Prometheus, an alternate title to give a hint of the theme. In library cataloging the subtitle does not include an alternate title which is defined as part of the title proper; e.g. "One Good Turn" (title proper) "A Natural History of the Screwdriver and the Screw" (subtitle); "Twelfth Night, or What You Will" (title proper).
