From The Poynter Institute:
The New York Times Public Editor Margaret Sullivan got her wish: The New York Times has a clear policy on quote approval. The paper will no longer allow sources to change quotes after an interview.
Quote approval “puts so much control over the content of journalism in the wrong place,” Times Executive Editor Jill Abramson told Sullivan. She quotes from a memo (see in full below) sent to staff:
"So starting now, we want to draw a clear line on this. Citing Times policy, reporters should say no if a source demands, as a condition of an interview, that quotes be submitted afterward to the source or a press aide to review, approve or edit".
