The descriptions of book grades that follow are intended to outline the relative condition of books in various states of preservation. These standards are based on trade practices recommended by The American Book Association to avoid misunderstandings in the buy, selling, and advertising of books.

BOOK GRADES

Grade of a book is usually shown in the form of VG/VG, Fine/Good, VG/--, etc. The first part is the condition of the book, the second is the condition of the dust jacket. If a "--" is present, it usually means that the dustjacket is not present.

C10 New. The finest quality available. A new book is unread, in print and in perfect condition with no missing or damaged pages.

C9 As New (AN). To be used only when the book is in the same immaculate condition to which it was published. There can be no defects, no missing pages, no library stamps, etc., and the dustjacket (if issued) must be perfect, without any tears.

C8 Fine (F or FN). Approaches the condition of As New, but without being crisp. For the use of the term Fine, there must also be no defects, etc., and if the jacket has a small tear, or other defect, or looks worn, this should be noted.

C7 Near Fine (NF ). Approaches the condition of Fine, but without being quite as clean and crisp, with perhaps the slightest shelf wear. For the use of the term Near Fine, there must be no defects, etc., and if the jacket has a small tear, or other defect, or looks worn, this should be noted.

C6 Very Good + (VG+). Describes a book that does show some small signs of wear - but no tears - on either binding or paper. Any defects must be noted.

C5 Very Good (VG). Describes a book that does show some small signs of wear - but no tears - on either binding or paper. Any defects must be noted.

C3 Good (G). Describes the average used worn book that has all pages or leaves present. Any defects must be noted.

C2 Fair (FR). Worn book that has complete text pages (including those with maps or plates) but may lack endpapers, half-title, etc. (which must be noted). Binding, jacket (if any), etc., may also be worn. All defects must be noted.

C1 Poor (P). Describes a book that is sufficiently worn, to the point that its only merit is as a Reading Copy because it does have the complete text, which must be legible. Any missing maps or plates should still be noted. This copy may be soiled, scuffed, stained or spotted and may have loose joints, hinges, pages, etc.
