Q: I live in the Nam-gu district, Busan, but can I still use the children’s library in the Suyeong–gu district?
A: Of course you can.
All of the public libraries in Busan are managed under an integrated system, aka 통합 시스템.
That means you can use any library in Busan.
And once you have a 이음카드, you can borrow and return books to any library in Busan.
이음카드 is not a credit card, but instead a library membership card.

You can apply for one at any library in Busan.
In just about 5 minutes you will have your own library card and can begin using the public library system.
Almost every gu-district has a children’s library.
Each one has a wide variety of books including traditional stories, modern fictions and imported English books. Go check them out.
