The following explains the condition standards for used books.
New: The book is unused, unread, and in perfect condition. It has no signs of wear or handling.
Like New: The book is in nearly perfect condition, with no major wear. There may be very minimal signs of handling or limited shelf wear, but the book remains unmarked inside and out, with no tears, markings, or highlighting.
Very Good: The book is clean and unmarked, but may show minor signs of wear, such as light scuffs, corner bumps, or slight creasing. It is free of major damage, such as tears or stains. A previous owner's name may be inscribed inside but does not significantly affect the book's overall condition.
Good: The book shows noticeable wear from consistent use. It may include markings, writing, or highlighting (up to 50% of the book). Signs of previous use may also include creased pages, a worn cover, or slightly loosened binding, though the book remains intact and readable.
Ex-Library: An ex-library book once belonged to a public library or institution. These books typically include library markings, such as stamps, barcodes, or catalog labels. They may also have a pocket for a checkout card or markings such as “Discarded” or “Withdrawn.” Aside from library-specific markings, the book will also be categorized under one of the general conditions listed above (e.g., Good, Very Good).
Ex-Libris: An ex-libris book contains a bookplate or label indicating ownership by a private library or individual. The bookplate is usually affixed to the inside cover and may include the owner’s name, initials, or artwork. Like ex-library books, ex-libris books will also fall into one of the general condition categories (e.g., Very Good, Good).
