Stockholm Public Library in Stockholm, Sweden-The first library in Sweden to adopt an open shelf design, the Stockholm Public Library opened its doors in 1928, when architect Gunnar Asplund and librarian Fredrik Hjelmqvist decided—to the joy of librarians all over the world—that library patrons could fetch their own books. Their self-service model was reinvigorated recently, with a renewed push toward automation for check-outs and returns. Photo: Marcus Hansson
