Book Patchwork is a collection of popular young adult literature from different countries that started with the books given by the Stockholm young adult library. Young Adult Library Services Association, a division of the American Library Association, contributed a list of the latest titles popular with young American readers, and RSLYA staff began selecting English-language books for young people. At the moment, the collection has books in English, German, French, Italian, Spanish and Swedish. The National Library for Children and Young Adults in Seoul, South Korea, has agreed to join the project.
