Booksellers use a standardized set of terms to describe book condition in their catalogs. These are: as new, a book in as perfect condition as when it was published; fine, a book without defects, approaching the condition of as new, but without being crisp; very good, a book showing small signs of wear but without tears on binding or paper; good, the average used and worn book with all pages present; fair, indicating a book with a worn binding whose text is complete but which may be missing endpapers, half-title page, or other individual leaves; and poor, a book so worn that its only merit is as a reading copy. Catalogs often abbreviate these terms and may present two of them together, separated by a slash — for example, fn/vg. In such a case, the first term describes the book and the second describes the dust jacket. If only one term is used, it can be assumed there is no dust jacket.
