Presumably the ones from the library, which the author mentions was his source? Every Pratchett book I read as a kid matched this description, including being battered.

Tell me more about this already-guilty-looking paper, and how this kid was "sliding" an entire paperback book into a math textbook with "a centimetre to spare".

I think I could slide this into a maths text book?

You wouldn't be able to open it and keep it open flat against the textbook though, not without the teacher noticing. It simply doesn't work, now that the author has acknowledged they used AI to spruce up their blog post, we can agree this part (hiding pocketbooks in open textbooks) was 100% slop.

I dont know what kind of pockets you have, but most Pratchetts book did not fit into mine. And yes there were whole series of books that fit. But, pratchetts ones did not.

I found this odd too. And the notion you could hide a Pratchett pocket book inside an open textbook. Anyone who has read Pratchett, or knows pocketbooks, knows this wouldn't work. They are voluminous (regardless of their name) and won't stay open on their own.

In fact, it seems a uniquely AI mistake to make to believe pocketbooks go in pockets. Anyone knows they don't fit, unless you have really big pockets and don't mind the weight and bulge.
