The problem is that it's still normal: http://en.wikipedia.org/wiki/Letter_case#Headings_and_publication_titles http://en.wikipedia.org/wiki/Letter_case#Headings_and_public... >As regards publication titles it is, however, a common typographic practice among both British and U.S. publishers to capitalise significant words (and in the United States, this is often applied to headings, too). This family of typographic conventions is usually called title case. For example, R. M. Ritter's Oxford Manual of Style (2002) suggests capitalising "the first word and all nouns, pronouns, adjectives, verbs and adverbs, but generally not articles, conjunctions and short prepositions"
