Like the gloss on the dust jacket is a bit off. VG - Very Good. Pretty darned nice. Might have one or two very small flaws. A bit of rubbing on the jacket.
Light shelfwear maybe.
But nothing that would actually qualify as a major defect. G - Good. A nice solid copy. This is what you would normally expect in a secondhand book. Might have a few defects, but certainly nothing missing, no severe problems.
