Textbook Authoring Insight: Percentage of Royalties to Offer New Coauthor on Long-Running Successful Textbook

We asked several veteran TAA textbook author members to respond to a fellow member’s inquiry on how to compensate a new coauthor, and we’re sharing those responses with all members who may find it helpful as they also grapple with this issue.

This was the question posed: A TAA author with a long-running, high-earning solo textbook is transitioning to retirement and is about to engage a junior coauthor. They plan to coauthor about two more editions before the senior author retires entirely. The senior author is seeking information or recommendations on the initial division of royalties—what percentage of the royalties to offer the new coming author for their first edition together, to be fair, incentivizing, and within professional norms.

Bartz v. Anthropic Copyright Case: Guidance to Anthropic Settlement Process for Educational Authors

TAA has new guidance for educational authors whose works are involved in the Bartz v. Anthropic Settlement but who are not eligible for the 50/50 default split, or for non-educational authors who chose to opt out of the 50/50 default split. Attorney Brenda Ulrich, with Archstone Law Group, has been working with TAA on providing this guidance.

TAA Advocacy Update: File a Claim on the Anthropic Settlement Before March 30

If you didn’t opt out of the Bartz v. Anthropic Settlement, it means your Work is still in the Settlement.

“Opting out” is not the same thing as not filing a claim. The only way to “opt out” was to complete an “opt out” form on the Anthropic website before February 9.

Each work has at least two potential claimants: you and your publisher. More if there are multiple authors.

TAA Shares Results of Survey Seeking Authors’ Experiences Filing Claims in Bartz v. Anthropic Settlement

Between December 2025 and early January 2026, the Textbook & Academic Authors Association conducted a survey seeking authors’ experiences filing claims in the landmark Bartz v. Anthropic settlement. The majority of respondents 87% (52) said they were educational/textbook authors, 23% (14) said they were university press/academic authors, 8% (5) said they were trade authors, and 3% (2) were unsure which author type they were.

While a majority of respondents to the survey said they had already filed claims (31 of 60), almost the same number of respondents said they had not (29 of 60).
