"In recent months, several publishers have announced that they are licensing their scholarly content for use as training data for LLMs. (...) To understand the dynamics around this fast-developing market, Ithaka S+R has launched a tracker of these licensing deals. In it, we catalog (when the information is available), the publisher, the purchaser, the deal type and size, and the impact of and strategy behind the deal."
