The most current edition of the Chicago Manual of Style, Associated Press (AP) Stylebook, Merriam-Webster’s Collegiate Dictionary, and Yale Web Style Guide Online are recommended as authorities for issues not covered in this guide.
When producing materials for use by the news media, follow journalists’ commonly preferred Associated Press style. AP style is a streamlined, fairly informal convention that uses no italics, less capitalization, and fewer commas than some standard styles.
Merriam-Webster’s Collegiate Dictionary
Not as comprehensive as Webster’s Third New International Dictionary; however, because it is updated more frequently, it contains recent usage changes.
