Legal Notice: "Dewey", "Dewey Decimal Classification" and "DDC" are registered trademarks of OCLC, who also claim all sorts of copyrights in the system, which is ridiculous considering that Melvil Dewey published his system in 1876, when Ulysses S. Grant was president. Nevertheless, OCLC has more lawyers than LibraryThing, and a penchant for suing to defend their control of library data, including Dewey, so we're posting this legal, if rather disrespectful, notice. The Melvil Decimal System, LibraryThing's effort to get around OCLC's control of Gilded-Age metadata is not a registered trademark.
