This 16th century German book opens in 6 different ways to reveal 6 books in one binding. It is a variation of a dos-à-dos (“back-to-back”) bookbinding, a rare method for attaching books back to back that was practiced primarily in the 16th and 17th centuries. The 6-way book is in the collection of the National Library of Sweden–there are more photos of it on the library’s Flickr page.
