Today’s circulating single-volume wonder was the barely-tolerable Encyclopedia of Strange and Unexplained Physical Phenomena (Jerome Clark, Gale, 1993).
It must be tough to put together such a work, as most such phenomena have no evidence whatsoever, though many readers may have beliefs. Clark ranged between absolute denial of claims and a believing awe of others. This editorializing wrecked the book’s credibility for me.
Probably the most heinous offense was the repeated use of quotations and testimony from Ivan T. Sanderson, who either ended up wrong (In the case of Jacko), or sputtered gibberish (as in his ‘penguin’ theory of the White River Monster). While Sanderson is likely a respected name in cryptozoology et cetera, the frequent mentions detracted from the authority of the encyclopedia.
