Isaac Asimov's Library of the Universe SCIENCE FICTION SCIENCE FACT . Gareth Stevens hardcover (1989) 4th MY GRADING SYSTEM FOR BOOKS I try to be fair and honest in my grading, and make every attempt to mention significant defects. Many old books will have a name written inside. Sometimes I fail to mention this, but I will gladly check for you at your request. 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 book, etc.; not too heavily worn, but shows an accumulation of wear, creases, etc. GOOD: complete, but well-used with worn edges and a greater accumulation of creases and other wear.
