While not directly associated with diving, I would also include Euell Gibbons' 1964 Stalking the Blue-Eyed Scallop.
From a previous thread --
"Gibbons, for those who don't recall, was a famous forager and naturalist, who arrived in California, during the time of the Dust Bowl; and the poor sod had to subsist upon scallops, limpets, spiny lobster, rock and Dungeness crab, abalone, and urchin -- being unable, according to one interview, to even afford grade-z hamburger meat, at the time . . ."
So too, The Essentials of Deeper Sport Diving by John Lippmann (1992), a longtime standard text, which deals with virtually all aspects of scuba, from the physiology of gas exchange; mitigating the risks of contracting DCS; nitrogen narcosis; crazy eye; bone necrosis; diving at altitude; and all manner of expected and unexpected emergency situations . . .
