This dictionary became preferred as a backup source by two influential style guides in the United States, although each one directs writers to go first to other, shorter dictionaries. "The Chicago Manual of Style", followed by many book publishers and magazines in the United States, recommends "Webster's Third", along with "Merriam-Webster's Collegiate Dictionary" for "general matters of spelling", and the style book "normally opts for" the first spelling listed (with the "Collegiate" taking precedence over "Webster's Third" because it "represents the latest research"). "The Associated Press Stylebook", used by most newspapers in the United States, refers readers to "W3" "if there is no listing in either this book or "Webster's New World"".
