I almost listed my RD Do It Yourself book but then I only reference it when something goes wrong that I haven't dealt with or at least, not recently. But it IS a great referrence when you need it. I might also list my reloading manuals, sky charts, pamphlet on knot tying, couple of chemistry books, Merck Manual, PDR, 2 vol. Egytian Heiroglyphic Dictionary, phone book, on and on. Gee, maybe I ought to start a library. No, that is what it is. Maybe a used book store! Yup, got my genealogy resources too. Somebody throw me a rope. No, that's alright. I know how to tie the knots!
