The New York Times Manual of Style and Usage

The New York Times Manual of Style and Usage: The Official Style Guide Used by the Writers and Editors of the World's Most Authoritative Newspaper is a style guide created in 1950 by editors at the newspaper and revised in 1974, 1999, and 2002 by Allan M. Siegal and William G. Connolly. A revised and expanded paperback edition was published in 2002. According to the Times Deputy News Editor, Philip B. Corbett (who is in charge of revising the manual), there is a more current, online version of the manual that is used by Times staff, but this online manual is not available to the general public. Instead, an epub version is to be issued in early 2015 for sale to the public.

Some differences between the Associated Press's style manual and that of The New York Times are:

• The Times's uses double S's for possessives. This is a deviation from AP style.
• The Times's manual gives rationale for many practices for which The AP Stylebook does not.
• The Times's guide is self-indexed, while the Associated Press's book has separate sections for sports and weather entries, and it combines many entries under such terms as "weapons" and "weather."
• The Times's book has some whimsical entries, such as one for how to spell shh.
• The Times's book requires that the surnames of subjects (sports-related articles being the most notable exceptions) be prefixed with a courtesy title (such as Dr., Mr., Ms., or Mrs.).

The style guides of Dow Jones & Company and The Wall Street Journal are similar to The Times's counterpart (WSJ also adheres to the AP style manual), but they have those differences given above.
