Mr. Whiting has combed all the obvious sources and hundreds of out-of-the-way publications of local journals and historical societies. This body of material, "because it covers territory that has not been extracted and compiled in a scholarly way before, can justly be said to be the most valuable of all those that Whiting has brought together," according to Albert B. Friedman. "What makes the work important is Whiting's authority: a proverb or proverbial phrase is what BJW thinks is a proverb or proverbial phrase. There is no objective operative definition of any value, no divining rod; his tact, 'feel,' experience, determine what's the real thing and what is spurious."
