BISAC Subject Headings
If you’re working on a simple taxonomy of legal topics, you might take a look at the Book Industry Standards and Communications (BISAC) subject headings for law. A couple of U.S. public libraries have caused a fuss by abandoning the Dewey system (which, it’s argued, was always meant to be “middleware”) in favour of more user-friendly taxonomies, among them the Book Industry example, used at big bookstores.
