The 404media article mentions notably https://nltimes.nl/2026/06/25/rare-book-dealers-fear-tech-fi... which says:
> The attachment contained 3,000 English-language titles organized by ISBN number, including books such as Distinct Element Modelling in Geomechanics by K.R. Saxena (1999); Barrett's Traditional Fairy Tales (2021), an academic study of Irish folklore; and Laser Shock Peening of Advanced Ceramics by Pratik Shukla (2018).
Non of those are rare. All a available in libraries for ILL.
so... not rare, then? another fear mongering article lying to everyone.
> Barrett's Traditional Fairy Tales (2021)
How is a book from 2021 considered rare in this context? There's almost certainly a digital copy of it in existence prior to Anthropic purchasing a print edition.
