在德国，一排排公共书架正在走入人们的视野。

Take a book, leave a book. In the birthplace of the printing press, public bookshelves are popping up across the nation on street corners, city squares and suburban（郊区） supermarkets.

In these free-for-all libraries, people can grab whatever they want to read, and leave behind anything they want for others. There's no need to register, no due date, and you can take or give as many as you want.
