The Seoul Metropolitan Office of Education Children's Library is a public library for children next to Sajikdan. Its three buildings—the Infant Hall, the Materials Hall, and the Culture Hall—lend books and collected works for kindergarten and elementary school students, with many new releases as well. It was established on May 4, 1979, and has seating areas for reading and a paid parking lot. In summer, the cooling is weak and the waiting area is hot.
