I'm not sure about other countries. There is a culture refuse to throw away books in Germany. People would put on the streets for free (I found two interesting books with this method).
German book culture is great! When he was in Karlsruhe to profile Peter Sloterdijk, The New Yorker reporter Thomas Meaney seemed surprised by it:
"Over the summer, ordinary Germans who spotted his [Peter Sloterdijk] books in my hands engaged me in conversation on trains, in coffee shops, at universities, and in bookshops." [0]

Every now and then I need to go to the recycling station here in Denmark. They have a special container/dumpster just for books. The second hand shops will take a small quantum of books, stores the buy and resell old DVDs, games, records, porn, comics and what-not, no longer buy books as there's no profit in second hand books. The dumpster is always overflowing with books, books that you're not allowed to take.
Germany is a lot more conservative than Denmark, so I wouldn't be surprised if they where more reluctant to throw out books. On the other hand, other than myself, how many people really want to read random novels from the 1970s or a 140 year old book on economics, telling you that Trump is wrong about tariffs?
Maybe with the advent of LLMs, old books will get a resurgence. If a book is printed in the 20th century, at least I know it's written by humans.
I mean what are they going to do? Burn them? Oh wait...

In the US people put "Little Free Libraries" in their yards. They're all over the place in the Seattle area.
