Hey, Anthropic owes me $9000! They illegally used at least 3 of my books on LibGen to create Claude. Now they're paying a $1.5 billion settlement, at $3000 per book. See if *your* books are on the list:

https://www.anthropiccopyrightsettlement.com/

If so, you have until March 23, 2026 to file a claim. The above website lets you file a claim, but this one explains everything more clearly:

https://authorsguild.org/advocacy/artificial-intelligence/what-authors-need-to-know-about-the-anthropic-settlement/#next-steps

Actually I exaggerated: the payment will be split between authors and publishers, but I have to make the claim - so the settlement is making me do some work my publisher should be doing for me. My coauthors and I will just get half, $4500. One of these books has 2 coauthors, one has 3, and one is a book I edited, with essays by lots of authors. So $1000 is a more realistic estimate of what I get. Oh well.

Bizarrely, my most popular book, Gauge Fields, Knots and Gravity, is not on the list. But I guess it's not surprising:

"The settlement agreement discloses that approximately 500,000 titles out of the 7 million copies of books that Anthropic reportedly downloaded from LibGen and PiLiMi meet the definition required to be part of the class."

Only books whose copyright is registered with the US Library of Congress meet that defiinition!

If you have a book on the list, you can opt out of the current settlement and join future lawsuits. But you have to take action to do that!!! For more information on that, see item 40 here:

Suggestion: I think you should consider putting your website and blog behind Cloudflare if they are not already, and use it to block AI crawlers or use their pay-per-crawl service https://blog.cloudflare.com/introducing-pay-per-crawl/

Same for mathstodon.xyz btw. @christianp

@maxpool - I'm actually trying to maximize distribution of my personal essence before I die. For example: everyone please take copies of 2616 pages of my writings on math and physics here:

https://math.ucr.edu/home/baez/TWF.html

But that's just me: I've *decided* to give away my work for free. I'm not in favor of AI companies, or for that matter publishing companies, exploiting the work of authors against their will.

@maxpool - so far I have been too lazy to do Creative Commons licenses for all my output. I should really hire someone to do it.

@maxpool - this sounds like it works for webpages and posts run by Wordpress. I have tons of my pages on my UC Riverside website, and also many files, like papers. My webpages are in crude HTML, not CSS.

Alas, I don't want to think about this stuff much: my desire to do new math and physics always trumps my desire to faff around with software.

I can, however, afford to pay someone to do this stuff. I need to find someone trustworthy, intelligent yet not too expensive.
