The wording above is the version this site observed on 2026-10-28. The source may have been edited after 2025-03-20. This page does not claim the wording was captured then.
What the claim commits to
- Kind
- Observation
- Deadline, as the speaker wrote it
- None stated. This site does not add one.
- Deadline state when assessed
- No horizon
- Deadline state on 2026-10-29
- No horizon (the release’s reference date)
Conditions
- in the Libgen database alone (qualifier, stated by the speaker)
From the speaker
- in this one database alone
- Meta pirated
- over 100 of my books and scientific articles
Our interpretation
- The database is LibGen. The threshold is at least 101 works authored or coauthored by Gary Marcus.
- The ordinary factual reading is that Meta acquired unauthorized copies of these works from LibGen. A catalog listing alone does not establish Meta's acquisition.
- Repeated records for the same work do not automatically count as additional works. Editions and translations require identification.
- The observation concerns acquisition completed by the post date. No starting date is specified, so the target period has an unspecified start.
- The word 'pirated' also suggests illegality. The factual acquisition assessment does not substitute for a copyright ruling.
Counts as supported if: Dated catalog records and Meta acquisition records identify at least 101 Marcus works copied from LibGen by March 20, 2025, without authorization for those copies.
Counts as contradicted if: A sufficiently complete acquisition and rights record establishes that no more than 100 Marcus works meet those conditions.
Retrospective: these criteria were written after the outcome was public.
Current assessment
Was it true for the period described?
Outcome: Unresolved
The record was checked, and the evidence available by the cutoff does not settle it.
Scored on a plain reading. The speaker named no measure for this claim, so it was judged on the reading an informed reader would take, stated below under our interpretation. Both reviews had to find that reading fair.

Rationale
The court record establishes broader downloading and training activity, but it does not verify Marcus's count. The Atlantic search tool was inaccessible to read_page, and the searches did not produce an independent list matching at least 101 Marcus works to Meta's downloads. Neither the threshold nor its negation is established.
Limitations
- An inaccessible source is an evidence gap, not evidence that Marcus was wrong.
- The legal meaning of 'pirated' requires a separate assessment of infringement and applicable defenses.
Evidence (1 item)
Context only: United States District Court, Northern District of California; copy hosted by UC Irvine,
Meta added the books it downloaded
Why it matters here: The court's retrospective account confirms the broader downloading and training activity. This item is dated to the judicial finding and is context only: it does not establish which Marcus works were acquired before his post.

What would settle it
A dated, deduplicated Marcus catalog list matched to Meta's acquisition records and relevant authorization records, sufficient to establish at least 101 qualifying works or a complete total of 100 or fewer.
