Already done

Sir, - David Crystal looks forward to someone making "an index supplement" to A. P. Cowie's Oxford History of English Lexicography (October 9). It has already been done: Google Books is giving away the index on its website and there Crystal can find out just where Cowie covers "the redoubtable Moore, Meech and Whitehall" and the American Samuel Johnson, who wrote a schools dictionary in the late eighteenth century.
