Capitalization

2.1.6 Capitalization

Capitalize the first letter of each major word in titles and subtitles. Do not capitalize articles (eg, a, an, the), prepositions of 3 or fewer letters, coordinating conjunctions (and, or, for, nor, but), or the to in infinitives. Do capitalize a 2-letter verb, such as Is or Be. Exceptions are made for some expressions, such as compound terms from languages other than English and phrasal verbs:
