Building Applications with Cornerstone, vintage computer game book. Companion piece to Infocom's database software. Seems to have had a low print run, and I suspect many unsold copies were destroyed when the software flopped. Has some wear from use on the cover, but the inside pages are all in great shape. Overall condition is VG using MobyScale grading. FREE insured shipping anywhere in the United States. International shipping will vary by destination. I welcome lower offers, especially if you are buying multiple items at once. To make a lower offer, add the item(s) to your cart and on the checkout page you will be given the option to name your own price. (If you are not seeing this option, it may be because your state requires sales tax. Bonanza is working on a fix for this issue, but you can also send me a direct message with your offer.)
