Generally prefer under-capitalization to over-capitalization. Studding a document with gratuitous capitals makes it hard to read. Capitalize only principal words: nouns, pronouns, adjectives, adverbs, verbs and prepositions of four letters or more.
For most U of G-specific capitalization rules, see “Titles and Names.”
For external communications written for an audience outside the University such as the media, use title case (capitalize only initial letters, everything else lower case) in headlines: Prof Discovers Ways to Help Heart Failure Patients.
For internal communications written for the University community, use either sentence case (capitalize only the initial letter of the first word) or title case, but be consistent. Sentence case: Prof discovers ways to help heart failure patients.
In headlines, capitalize principal words (nouns, pronouns, verbs, adjectives, adverbs, and the first and last words of the title). Capitalize even small verbs and nouns: Is, Are, Be, It, etc. Also capitalize prepositions and conjunctions of four letters or more: Food From Thought (not: Food from Thought).
In a headline, don’t capitalize articles (a, an, the) or prepositions and conjunctions of fewer than four letters: Food for Thought. Capitalize these short words (for, to, at, in) only when they appear as the first or last word in a title or when they appear immediately after a colon or semicolon.
If a title is in French, only the first word is capitalized.
If a title contains hyphenated words, capitalize both words: New Book Tells Story of History-Filled Guelph Guitar (not: History-filled).
