A visual indication, often a pen stroke or stamp, applied to the edge of a book’s pages, typically the bottom edge. This mark signifies that the book was sold by the publisher to a remainder dealer at a significantly reduced price, often due to overstock or a title’s declining sales. The presence of this mark generally indicates that the book is non-returnable to the publisher. As an example, a black line across the bottom of a hardcover signifies it was sold at a discount.
Such markings are important for several reasons. They allow publishers to clear excess inventory without disrupting the retail price of books still being sold at full price. From a consumer perspective, the presence of the mark can signal a bargain, allowing access to books at a more affordable cost. Historically, this practice has allowed publishers to manage unsold inventory effectively, preventing warehousing costs and potentially recouping some revenue from titles that might otherwise be destroyed. For collectors, the existence (or absence) of a remainder mark can sometimes affect a book’s value, depending on its rarity and condition.
