Remainder Marks on Books

That little marker stripe across the bottom edge of the pages has a name and a story — and it quietly affects what the book is worth. Here's what it means.

Book-Condition Library

A remainder mark is a mark — usually a felt-tip line, a sprayed dot, or a small stamp on the page edges (most often the bottom) — that publishers add when they sell unsold overstock cheaply as "remainders," so those discounted copies can't be returned for full credit. It's cosmetic provenance, not damage to the text, but it does lower a book's value to collectors, who prefer unmarked copies. It's one of the most common little mysteries people notice on a shelf.

Remaindered books are welcome. A black dot or a stamp on the edge doesn’t matter to me: every book goes in my covered 24/7 drop box on Edith Blvd NE, free, or rides a free metro pickup. Text 505-250-3804.

What the mark is — and why it's there

When a book doesn't sell through, the publisher eventually clears the overstock at a deep discount; those copies are "remainders," and they're what fills the bargain tables. To keep someone from buying a cheap remainder and returning it to a bookstore for the full cover price, the trade marks remaindered stock so it's identifiable. That mark usually lands on the bottom edge of the closed text block — a swipe of permanent marker, a sprayed dot or stripe, or sometimes a small stamp. You'll occasionally see it on the top or fore-edge instead. It says nothing about the printing or the content; it's purely a record that this particular copy came through the remainder channel.

Where to look for a remainder mark

Publishers and wholesalers mark remainders where it’s fast and visible, so you almost always find the mark on one of the page edges: the bottom edge (most common), the top edge, or the fore-edge (the side opposite the spine). Hold the book closed and look at the three outer edges of the text block — a remainder mark is a deliberate line, dot, spray, or stamp in marker or ink, running across the closed pages. On paperbacks it’s sometimes a clipped or slashed corner instead. It is not on the pages inside, and it’s not the same as a price sticker or a previous owner’s name.

Common forms: a single felt-tip line or dot, a sprayed dot of color, a small stamp, or a series of slashes. Any of them means the same thing — the book was sold off as overstock rather than at full wholesale.

Sellers are supposed to tell you. The condition definitions published by the Independent Online Booksellers Association treat remainder marks as a fault that must always be noted, so look for “remainder mark” or the abbreviation “rm” in a listing. For where a marked copy lands on the overall grade, see my book condition grading guide.

Remainder mark vs. damage vs. book-club

Three things get confused, and the difference matters when you’re deciding whether a book is worth listing. A remainder mark is a clean, intentional publisher mark on the edge; the book is otherwise new and unread. Damage (water, foxing, a cracked spine) is condition wear, and it lowers value in a way a remainder mark mostly doesn’t for reading copies. A book-club edition is a different printing entirely (usually no price on the jacket, a blind stamp or dot on the back board, smaller and lighter than the trade edition), and that does change collectibility. A remainder mark on a genuine first printing is far better news than a book-club copy of the same title; the remainder is still the real first edition, just marked.

Do remainder marks lower value?

Yes, to collectors. A remainder-marked copy is worth less than a clean copy of the same book, because collectors want a copy that looks like it was never discounted overstock. How much less depends on the book: for ordinary titles the difference is small (they were low-value either way), but on a collectible first edition, where buyers are paying for a near-flawless object, a remainder mark is a real demerit that can meaningfully cut the price. The good news is that the mark doesn't touch the text or the reading experience at all.

Don't try to remove it. Sanding, bleaching, or scraping a remainder mark off the page edges almost always leaves visible damage — uneven edges, discoloration — that experienced buyers spot immediately and that's worse than the original mark. Leave it alone.

What a remainder mark is not

It's easy to confuse the various "this copy is different" signals, so to keep them straight: a remainder mark is overstock provenance on the page edges; a book club edition is a cheaper reprint with its own tells; an ex-library book carries stamps and pockets; and a price-clipped jacket has had its price corner removed. Each affects value differently, and a single book can have more than one.

And the bottom line for clearing a shelf: a remainder mark is not a reason to skip donating a book. Marked or not, bring it — it reads exactly the same, it's perfectly good for circulation, and if it happens to be a marked copy of something genuinely collectible, I'll still spot it. You don't have to judge any of it. Remaindered hardcovers, bargain-table buys, and everything else on the shelf can go in the covered 24/7 book drop at 5445 Edith Blvd NE or out the door with a free book pickup anywhere in the Albuquerque metro; outside New Mexico, ship the books to me by Media Mail (you cover postage).

Frequently asked questions

What is a remainder mark on a book?

A mark (felt-tip line, sprayed dot, or stamp) on the page edges of overstock sold cheaply as remainders, added so the discounted copy can't be returned for full credit. It's cosmetic, not text damage.

Do remainder marks lower value?

Yes, for collectors: a marked copy is worth less than a clean one. The difference is small on ordinary books and larger on a collectible first edition, and the mark has no effect on reading.

What is a remaindered copy?

A remaindered copy is a new, unread book that the publisher sold off cheaply as overstock after the title stopped selling at full price. Most remaindered copies carry a remainder mark on the bottom edge, though not every copy gets one. When a listing says remainder mark or rm, it means the copy came through that bargain channel, not that it was read or damaged.

Who puts the remainder mark on a book?

Usually the publisher or its warehouse, when it clears overstock to bargain-book distributors. The mark goes on before the books are resold so that a discounted copy can't later be returned for full credit. Booksellers who buy remainders simply pass the marked copies along.

Can a remaindered book still be a first edition?

Yes. Remainders are leftover copies of whatever printing was sitting in the warehouse, so a remaindered copy of a book that never went back to press is a true first printing. The mark lowers the copy's collector grade, and careful sellers always note it, but it does not change the edition.

Should I remove a remainder mark?

No — attempting removal usually causes worse, obvious damage. Leave it as it is.
