For heaven's sake--I thought I wouldn't find anything of interest to me, but my first hit garnered this:
It is proper to observe that the existence of isonomia as an anachronism in the Harmodius song, though it proves that the skolion is not archaic, fails to prove that isonomia could not have been an old word in use in the last part of the sixth century as a political expression. In fact, there is reason to infer the contrary—if, that is, Herodotus is a reliable guide and we interpret him correctly.

Also, it looks to me like the 3 indices listed should make it easy to locate many things.
