The International Library of Children’s Literature (ILCL) passed its 15th anniversary this year, since its establishment on Children’s Day (May 5) in 2000. The year 2015 has become a significant milestone for the ILCL, with the completion of a new annex building at the end of June, after approximately three years of construction from February 2012. The annex building, the “Arch Building,” stands in face to face with the existing building, the “Brick Building.”
In establishing the Arch Building, we decided to classify the functions of the ILCL facilities into three roles. The Brick Building, with the users’ entrance, will be a place for everyone to get in touch with children’s literature. It is assigned (1) the role to provide a venue to enhance interaction between children and books, and (2) the role as a museum of children’s literature. The Arch Building, which is reached through the Brick Building, assumes (3) the role as a library specialized in children’s literature.
