In nearly every household they are to be found – old books not read for quite a long time. books are mostly presented in a shelf like trophies or remembrances although they probably will never be read again. This book shelf offers for these books which became precious just a new presence and aditional function in the special "shelf architecture". A quite arbitrary number of shelf boxes in different heights, cutting and turning round each, are forming this shelf. Every crate is oriented in its height and depth on a pair of books and forms an individual frame for it. Put into grooves, with an extended lid each, the books are forming small hinged storage spaces in the shelf.
