@DPittman Interesting point of view -- goes to show how tastes can vary. I'd figure that those would sell pretty quickly, depending on the audience it reaches. I like to read machining texts from the turn of the century, and often pick older and older copies of the same book....... If I didn't already have most of those......
I like PDF format for reference in the shop, but for -30 degree nights, with the wind howling, give me a fireplace, cup of tea and some old book any day. Same goes for magazines. My wife loves her iPad and her subscriptions, but all mine come in the mail!
