I recently got into a debate with a fellow editor about whether or not to send completed drafts to the subjects of an article. His belief is that it is not necessary to forward people the pieces before publishing. Doing so would open up a floodgate of changes and as a result, many additional drafts.
I, on the other hand, think it's a wise move to let your interviewees weigh in on articles before they go live. It allows for the opportunity to fact-check your piece and promotes a greater trust and rapport with your subjects. If they took the time to provide you with dozens of quotes, shouldn't they have the right to look them over to make sure everything sounds eloquent and accurate? Just think of the headaches and edits you'll be saving later on, once the piece is published.
In many cases, I've had subjects remember important pieces of information when given the chance to look over an article. Added anecdotes and other pertinent revisions pave the way for enhancing the piece and engaging your readers.
