demonstration experimental catalog. ShelfLife uses the library's most familiar way of displaying works — shelves — but goes far beyond what real shelves can do. For one thing, ShelfLife shows on a single shelf all the holdings of all the libraries on campus. For another, it does not confine a work to a single shelf. With a click a user can see the same book shelved with other works under the same topic heading, with works by the same author, with works browsed by other users of the system, etc.
