I have a habit of pulling wire-bound books out of the shelves of thrift stores to take a peek at the covers. Usually they’re cookbooks, but I’m on the hunt for a book called “Rocky’s Typewriter Repair Manual” by Clarence LeRoy Jones, which I’ve never seen a copy of, but I expect it’ll be wire-bound. I take the invariable disappointment of seeing the titles of these wire-bound books in stride, but very, very occasionally I’ll get a little surprise.
Today’s thrifting trip held one such rare surprise. I pulled out a wire-bound book and found this:
“Slide Rule, A Textbook For Classroom and Self-Instruction” by C.L. Johnston, written in 1953, this is the Fifth Edition, published in 1972. It’s a complete course in using a slide rule, with extensive tests in problem solving.
I only have two slide rules, fairly simple ones: A Post 1447 Mannheim made of Bamboo in Japan in August 1954 (with original box!) and a more modern Pickett 1010-T made of aluminum. Neither are shown in the “recommended slide rules” section of the instruction manual, and thus I may have to hunt down a more complex and featureful model before taking on the course.
Speaking of which, since I know there are at least a few Typospherians with a slide rule addiction, I have scanned in that section for your enjoyment and reference. Click or download to embiggify, they’re pretty high-resolution scans:
