The Stockholm county library boat, or bokbåten

"The Stockholm county library boat (or bokbåten), visits 23 islands, including Möja, in the Stockholm archipelago, for one week twice a year. It carries around 3,000 books and a rotating staff of three to four librarians."

"When it docks, island residents have about one-and-a-half glorious hours to come aboard the motor ship, browse its treasures, and borrow anything they’d like. Each 'island has one library card and, in a delightful detail, there are no penalties if a book isn’t returned six months later."

“The Scandinavian countries have a long history of [the] welfare state where literacy and learning are considered important,” says Päivi Jokitalo, a Finnish library specialist. “The library systems stress equal access to literature and knowledge for all, regardless of background.”
