I am a librarian in Taiwan.I want to know the teens service in public library in your country. Thanks a lot.

You can borrow books and different items. You can read, do your homework or listen to music or audio books. You can use the computers to surf the net or to play games. There are also board games and toys in some libraries. The library is a very good place to meet your friends, too.
