Here people even "steal" books from public bookcases and sell them.

For people who aren't familiar, let me explain: These public bookcases are a weatherproof shelf, old phone booth or something in the streets. The concept is you can take any book and leave any book. There are no written rules and you can keep a book if you like or just read it and put it back. In recent years people started to scan the barcodes and checked what books they can sell. There is a debate going on if people should mark these books or not, so they can't be sold.
