MDS: The "I fervently hope that's a typo" thread

I was looking around at various headings on the Dewey browser, when I stumbled on this oddity: listed under 654 ("Telegraph; Cables; Signals") is The Art of New American Cooking

I hope whomever is responsible for this meant to put this in 641.5 ("Cookbooks").

Oy. Under 669 I found an adaptation of J.M. Barrie's Peter Pan
