Anthropic Copyright Settlement Lookup: Works List and Claim Status

Settlement at a glance

The lookup belongs to the $1.5 billion class settlement in Bartz v. Anthropic, No. 3:24-cv-05417 (N.D. Cal.), which received final approval on July 20, 2026. The class covers rightsholders of books Anthropic downloaded from the pirate datasets Library Genesis and Pirate Library Mirror, and the administrator built a searchable Works List so owners could confirm coverage before filing. That list is the boundary of the class: the final approval order repeats that only works included on the Works List are in the class.

This page explains how to use the official lookup and what to do with the result. It does not host or reproduce the list, and it is not affiliated with the court, the parties or the administrator. Payment amounts and dates are covered on the payout page, and the full terms on the settlement explainer, both in the related links.

Who qualifies

Works on the list

A book appears on the list only if it meets every condition in the court-approved class notice: Anthropic downloaded it from LibGen or PiLiMi, it has an ISBN or ASIN, it was registered with the U.S. Copyright Office within five years of first publication, and it was registered before Anthropic downloaded it or within three months of publication. Class counsel’s April 2026 claims report counted 482,460 works on the list (Dkt. 643). Many books that were never registered, or were registered late, are not on it even if Anthropic downloaded them.

Authors versus publishers

Each listed work can have several owners: authors, co-authors, publishers, estates and loan-out companies. All of them share one per-work award. For trade and university press books the default is a 50-50 author and publisher split. The lookup’s directory marks which works are Education Works; those have no default split, and the share follows the publishing contract or the dispute process.

How to file or check a claim

Using the official anthropic settlement works list

1. Go to the official Works List Lookup by typing the address yourself, or from the menu on AnthropicCopyrightSettlement.com.
2. Choose a search type: ISBN or ASIN, title, author full name, publisher name, or copyright registration number. An ISBN or registration number gives the most precise match.
3. If an author search fails, try a pen name or legal name. The class notice says the list was compiled from copyright pages and registrations, which often record both.
4. Read the administrator’s search tips if results look incomplete, and check each edition’s ISBN separately.
5. Note whether the result is flagged as an Education Work, since that changes how the payment is split.

Anthropic copyright settlement claim form

The claim form is still posted on the administrator’s Important Documents page, but the filing window closed on March 30, 2026. If you filed, there is nothing new to submit; if you did not, the official options page explains that you may still be paid if another rightsholder for the same work filed a claim confirming your right to payment. If no one filed for the work, no payment will be made for it, and the claims the settlement resolves are released.

Class counsel told the court in September 2026 that a small number of late-claim requests had arrived since the final approval hearing and would be submitted for the court’s review (Dkt. 688). There is no published late-claim window; anyone in that position should contact the administrator directly.

Correcting or disputing a claim

Each claimant received a consolidated form listing their percentage share of every claimed work, according to Dkt. 688, with a period to contest it. IP Law Daily reported that the response period was extended from 30 to 60 days and was expiring in the first week of November 2026. Changes are made in the administrator’s allocation portal; the court-approved FAQ text quoted by Publishers Lunch says portal changes are reviewed manually and do not appear right away. Disputes that co-claimants cannot settle go to the court-appointed Special Master.

How much and when

Class counsel estimates the first distribution at about $2,203.56 per claimed work, before the split among rightsholders, and the parties expect to send it during the week of November 23, 2026 (Dkt. 694). A second round should follow after Anthropic’s final installment, due by September 2027. The payout page in the related links breaks down the per-work math, the split and the reasons a payment can be delayed.

Is it legitimate

The lookup and the settlement are real and court-supervised. JND Legal Administration was appointed by the court and its appointment was reaffirmed in the July 20, 2026 final approval order, which also found the notice program met due process. The official lookup sits on the secure subdomain of AnthropicCopyrightSettlement.com, and the administrator lists 1-877-206-2314, info@AnthropicCopyrightSettlement.com and a P.O. box in Seattle as its contacts.

Third-party pages, including this one, cannot tell you whether a claim was accepted or what you will be paid. Only the administrator can. If a book is not on the list, the Authors Guild’s summary of the final order notes that claims over unlisted works are preserved and unaffected by the settlement. For broader context on authors’ rights, see the rights hub. This page is general information, not legal advice.

Frequently asked questions

How do I check if my book is in the Anthropic settlement?

Use the official Works List Lookup at secure.anthropiccopyrightsettlement.com/lookup. Search by ISBN or ASIN, title, author, publisher or copyright registration number. If your book is not listed, it is not in the class and your claims about it are not released.

How do I claim the Anthropic settlement?

The claim deadline was March 30, 2026, so new claims are closed. If a co-owner of your work filed and confirmed your right to payment, you may still be paid. Late-claim requests are reviewed by the court case by case; contact JND Legal Administration at 1-877-206-2314.

Where is the Anthropic settlement book list?

The list is searchable only through the official Works List Lookup on AnthropicCopyrightSettlement.com, run by court-appointed administrator JND Legal Administration. Independent sites, including this one, do not host the official list.

Can I still file an Anthropic settlement claim?

Not through the normal process. Claims closed March 30, 2026. Class counsel said in September 2026 that a small number of late-claim requests would go to the court for review, but there is no open late-claim window as of November 9, 2026.
