THE UPANISHADS BREATH OF THE ETERNAL Mentor paperback (1961) 4th MY GRADING SYSTEM FOR PAPERBACKS I try to be fair and honest in my grading, and make every attempt to mention loose pages, stains, binding damage, etc. Please understand that the glue used in the binding of old paperback books was not designed for longevity; when old paperbacks are opened for reading, additional pages may loosen at that time. Used bookstore stamps are often found inside the front cover of used paperback books. FINE: in exceptional condition; not perfect, but very high grade. VERY GOOD+: still nice, but showing its age; some overall wear. VERY GOOD: the average used paperback; not heavily read, but shows an accumulation of wear and creases. Fore edge, top and bottom may have light spotting. Spine may also be creased from reading. GOOD: a complete copy, but well-read with worn edges and a greater accumulation of creases and other wear.
