@nprofile1q... most libraries try to avoid buying ai generated books or books with contents parcially generated by AI.
If I had to guess, most AI generated contents can be found in academic libraries. Children's library sections struggle with AI illustration above all, although I have also come across books clearly style-corrected by chatbots. I think the overall consensus is to especially keep children's sections free from AI generated crap.
Curious: which book was it?
