These are mass-market paperbacks (about 4" x 7") except for one which is a small hardcover about the same size as the paperbacks.  On a scale of poor, fair, good, very good, and excellent condition, the books range from good to good-plus.  All the books have clean intact covers and strong bindings.  Covers may have normal wear (some corner-wear, edge-wear, spine creases) but no damage.  In one or more books the insides of the covers, and the pages, may have some age-tanning, and one or more books may have a former owner's name or other very minor markings not affecting the text.  Otherwise, pages are clean with no writing, highlighting, underlining, or odors.  These are NOT ex-library books. 

These books should be considered reading copies only, and are not intended as collectibles or a complete, consecutive, or matching set.
