The New York Times Manual of Style and Usage is a style guide (copyright 1999) by Allan M. Siegal and William G. Connolly.

Although it was written for The New York Times journalists, it has also been published for use by others. Much of the information is specific to either The Times or New York. But much of it is also useful for general audiences.

Some difference with the Associated Press style book are:

• The Times' manual gives rationale for many practices that the AP stylebook does not.
• The Times' guide is also self-indexed. AP's book has separate sections for sports and weather entries, and it combines many entries under such terms as "weapons" and "weather".
• The Times' book has some whimsy, such as an entry for how to spell "shh".
