You’re supposed to believe it’s factual because you have investigative reporting by multiple newspapers with good track records, on the record statements by bookstore owners, and evidence presented in court cases like the one regarding Anthropic’s Project Panama.

Notably, one of those piece of evidence from that Anthropic case was an internal presentation clearly stating the intention of Project Panama was to “destructively scan all the books in the world.”

Beyond that, some book sellers have named specific titles, such as “an Estonian translation of John le Carré's The Mission Song, a specific edition of Anne Brontë's Agnes Grey, and the October 1983 issue of Warship monthly magazine” and “everything from 18th-century African agricultural implements to biographies of 1950s racing drivers.”[0]

But getting a full list of all those sold globally is difficult. I imagine we’ll start to see some efforts to try to encourage booksellers to contribute to public lists though.
