The one on the left is in good but used original condition except for small torn piece on cover - 165 pages with index.
The right one is well used in fair condition with 145 pages - no index so possibly 1st edition. Priced as a set of 2 for $150 USD and that includes postage. There are more Apple/Macintosh books available - click the book label below. To inquire contact Dave via kootenaymac.tel
