Quality of Goods
The condition of books sold by us are listed as follows:
MINT: like new
FINE (F): the book is in excellent condition. Closer examination will show evidence of ownership and/or storage. There may be a small inscription or the name of a previous owner. Generally the book will be in near perfect condition. A fine dustwrapper will also be in excellent condition with very slight rubbing at the corners.
VERY GOOD (VG): slightly less than fine condition but still acceptable to many collectors - the book may have minor faults such as slight fading or foxing, minor bumps or wear but there are no major faults. A VG dustwrapper will be without tears or chips. It will be clean and bright. There may be slight rubbing to corners and edges.
GOOD: the book will be obviously second-hand and well used but will be complete in all respects unless otherwise described. A good dustwrapper will be fairly clean, but may be creased or marked. The edges may be rubbed and worn and may have small tears.
POOR: reading copy only.
