The Flack quotes a pair of FBI agents on tips for good interviewing. BL Ochman has some excellent advice for how to protect yourself from being misquoted. I especially agree with her about taping oral interviews.
Email interviews produce colder, less interesting copy. Live interviews, in person or over the phone, produce better copy, so I encourage clients to agree to them.
Preparing for an interview is also very important. Preparing for an interview isn’t about spin and canned messaging. Preparing is about thinking about the audience of that particular publication and what it is you wish to communicate to them.
