Over the past several years major publishers have been moving away from physical or electronic books into online learning platforms and courseware, and from straight sales of standalone books to bundles, custom products and subscriptions. Traditional publishing contracts were developed at a time when a book was a discrete unit, sales could easily be tracked in those units, and revisions occurred on a predictable cycle. Publishers are trying in various ways to update and adapt their contracts to the new textbook landscape. In her 2023 TAA Conference session, presenter Brenda Ulrich, an attorney at Archstone Law Group, will explore the ways in which the contracts are changing, and what the implications are for authors.
