I Sunsin Library is in Ungcheon-dong, Yeosu, and opened in 2020. Books are arranged so they are easy to find, and the building holds reading rooms, a lifelong learning center, and a coffee shop on the second floor. The individual reading rooms require a membership on the Yeosu City Library website or a library card, while the open reading room can be used without a card. The range of book titles is not very wide.
