Unknown Quantity: A Real and Imaginary History of Algebra

We are very proud of the condition of the books we sell (please read our testimonials to find out more!)

New: Exactly as it says.

As New: Pretty much new but shows small signs of having been read; inside it will be clean without any inscriptions or stamps; might contain a remainder mark.

Very Good: Might have some creases on the spine; no hard cracks; maybe slight forward lean and short inscription inside; perhaps very minor bumping on the corners of the book; inside clean but the page edges might be slightly yellowed.

Good: A few creases on the spine, perhaps a forward lean, bumping on corners or shelfwear; maybe an inscription inside or some shelfwear or a small tear or two on the dustjacket; inside clean but page edges might be somewhat yellowed.

Fair: In overall good condition, might have a severe forward lean to the spine, an inscription, bumping to corners; one or two folds on the covers and yellowed pages; in exceptional cases these books might contain some library stamps and stickers or have neat sticky tape which was used to fix a short, closed tear.

Poor: We rarely sell poor condition books, unless the books are in demand and difficult to find in a better condition. Poor condition books are still perfect for a good read, all pages will be intact and none threatening to fall out; most probably a reading copy only.
