This is a general guide to my concept of each condition listed
Condition Guide:
New: New
Like New: Book looks almost new, has something extremely minor that makes the condition, not new.
Great: Minor Wear such as spine crease or very little lean, book looks read, overall condition is still very good.
Good: Has some reading wear ( appears read more than once), but still in good overall shape, more spine creasing, or lean. Pages are still clean, edges show some wear.
Fair: wear all around, looks well read
Reading Copy: good for reading, but not in any type of + condition, book can be read and thats all.
