At the awesome blog Awful Library Books, Michigan librarians Mary Kelly and Holly Hibner showcase old, bizarre books that probably shouldn't be in circulation. The blog contains many science, engineering, and computing texts. Here are some of the most lamentable.
In 1972's Science Projects You Can Do, George Stone teaches children that giving a guinea pig scurvy is a perfectly acceptable science fair project.
He also advocates electrocuting earthworms for no apparent reason.
Stone was nice enough to include a diagram on how to build your own earthworm torture device.
Linda Sullivan and Helen Sernoff's 1996 book Research Reports: A Guide for Middle and High School Students. "Although it contains vast amounts of information, the Internet will probably not be useful."
1989's Computer Virus Crisis by Philip Fites, Peter Johnston, and Martin Kratz teaches you to avoid virus-laden floppy disks. If an unwashed trucker swaggers into your bedroom and offers you a bag of suspicious disks, just say "no."
Richard Deming's 1973 Metric Power. A prescient tome.
1991's 101 Weapons for Women: Implement Weaponry: A Unique Concept in Women's Self-Defense, which teaches computer disk defense tactics.
James Schefter's Telecommunications Careers (1988) teaches you the joys of mobile communication.
Leon Whitney's Training you to Train your Cat (1968).
An excerpt from Tim Paulson's 1992 book, How To Fly a 747. Holy shit.
