It is more than just books published pre-2022, but I've noticed that it is necessary to buy books __printed__ before 2022. Recently I've noticed aggressive misspellings and misquotations in old books printed in '25/'26. I believe these errors are being introduced because the publisher is using an LLM or some similar tool to correct any prior errors but is introducing more hallucinations. Or perhaps the cause is people caring less than they used to?
