Wheildon gives statistical analysis that supports readers' preference for lowercase headlines over those which use uppercase for every letter. Since readers recognize letters by their tops, uppercase heads are more difficult to read (62.) We used lowercase headlines but capitalized the first letter of each word, but even this is considered outmoded by some. Roger Parker and Jan V. White recommend that you only capitalize the only the first letter in the first word of a headline and use lower case for the rest.
