Auction catalog

An auction catalog (US spelling) or auction catalogue (British spelling) is a catalogue that lists items to be sold at an auction. It is made available some time before the auction date. Auction catalogs for rare and expensive items, such as some art, books, jewelry, postage stamps, and antique furniture, are of interest in themselves: they will often include detailed descriptions of the items, their provenance, historical significance, photographs, and so forth.
