Headlines and Titles of Works

Q. I’m an event organizer, and one of the themes of my event is “creativity beyond the page.” Should it be “Creativity Beyond the Page” or “Creativity beyond the Page”? Can beyond be capitalized in this case?

A. Chicago style lowercases prepositions, but many style guides uppercase the longer ones. If you want to uppercase beyond, it isn’t incorrect. But take care to send a memo or style sheet—if anyone else on your team is using Chicago style, you may find your slogan presents an inconsistency in your publicity.
