If your standard textbook revision cycle has come and gone, it doesn’t automatically mean that you aren’t being revised, and you can’t expect that your publisher will reach out to you either, so you’ll need to ask, says Donna Battista, vice president of content strategy for Top Hat.

“Get in touch with your publisher and just ask directly,” she says. “I think it’s always good practice to start from the perspective that everybody is going to work in good faith. Nobody wants to squat on your rights.”
