The following grade definitions are taken from the Independent Online Booksellers Association Website.
[NOTE: From here on, there may be "+ (Plus)" or "- (Minus)" in a grade, which will mean that it is above the grade noted but not quite to the next higher grade for "+", and that it is below the grade noted but not quite to the next lower grade for "-", i.e., Very Good + (or Plus)/Very Good - (or Minus). Which means the book is better than Very Good and the dust jacket grade is less than Very Good.]
REMAINDER MARKS, BOOKPLATES, PREVIOUS OWNER'S NAME: These are faults and must always be noted, if they apply.
WE use "Fine" as our highest grade. followed by "very good". We do not use intermediate grades such as "near fine" or very "good +". It does not mean that our books are not as good as someone else's "near mint ++ wow" just that we think this confusing.
