How book quality is graded:

• New - brand new and never owned.
• As-New - with extremely little signs of use, no blemishes. This includes 'mint' condition vintage books with no sign of use.
• Excellent - minor signs of use, may be almost 'as-new' except for a single scratch, small tear or scuff. A healthy firm spine, pages are still well aligned. Excellent vintage books will have more signs of ware than recently published books.
• Great - very obvious signs of use, may have a single bent page or a some cover fading. Spine is still strong, but pages may not all line up perfectly when book is closed.
• Unsellable - books that I don't bother purchasing for resale and will not appear on this store; many bent torn or folded pages, great sign of wear, stains on pages, sticky/stuck pages, large tears, weak spine and/or lose pages destroyed front/back cover.

Some tanning or darkening of vintage book pages is not considered a sign of poor condition, this is an attribute of all aging books, just like the nostalgic 'old book smell.'
