Q: I’m a published author. I signed a textbook contract with a publisher 32 years ago and the first edition of my text was published 30 years ago. It’s since been revised 9 times, all under the original contract, and is due to be revised again soon. Recently, my publisher wrote and said they wanted to sign a new contract for the new edition because the industry had changed, their business model had changed, and the old contract was no longer in step with their current practices. Should I go along with this and sign the new contract?

A: Maybe. . . but not without doing a little homework first. Your original contract almost certainly contemplated that your text, if successful, would need periodically to be revised. What it probably said about this was that “if and when” the publisher thought a revision was warranted, the publisher would call upon you to prepare it. And if you were willing and able to do that, the revision would be prepared and published under the terms of your then existing agreement as if it were the work being published for the first time.
