The Rare Book trade is full of expressions that you may not have previously encountered, and which can seem somewhat intimidating to new customers or those unfamiliar with rare book cataloguing. Although it may not always seem like it, we are not deliberately trying to confuse and befuddle you, and most descriptions follow industry guidelines, using a long-established terminology, a cryptic puzzle which, once unpicked, will soon become clear and familiar.

At DCRB we take pride in the precision and detail of our cataloguing, which conform to the required standards of the Antiquarian Booksellers Association. Compiled by Roger Gaskell,  the ABA Terms of the Trade provides a more detailed and technical explanation for those wishing to learn more.

The International League of Antiquarian Booksellers also provides a useful guide, including translations of terms into French and German. A further glossary to some commonly used terms bookselling terms and abbreviations, has been compiled by ABA Past President Laurence Worms, owner of Ash Rare Books, and author of Cataloguing for Booksellers
