Q. It has baffled me for years why the name of The New Yorker is sometimes written the New Yorker, and today I learned it is because the Chicago Manual advises it. I’m not sure why. The title of the magazine, as William Shawn used to say, is The New Yorker. To present it otherwise is to make a factual error, as it would be to print the New York Times, or the first letters of someone’s name in lowercase.
A. As of the 18th edition, CMOS style for those titles is now The New Yorker and The New York Times. In source citations, however, the The can be omitted. See CMOS 8.172.
