This is a "very good" vintage trade paperback published circa 1986 by Collier Books, 450 pages. Spine is square, crisp, not creased, cracked or rolled. Text block and covers close tightly and flat. Board corner tips are mildly blunted. Thick text block edges are uniform in color all around, no significant faults, a few small dings in a few places. No writing, labels, no loose, torn or folded pages. Very nice vintage reference paperback! You don't see books of this type and vintage this nice very often. See accompanying images for full condition details. Will ship promptly, carefully packaged.
