Dezeen in Israel: designer Chanan de Lange exhibits two circular library bookshelves made from recycled school desks at the Tel Aviv Museum of Art.
Around 20,000 books can be stored on the wooden shelves, which are fixed at different angles onto supporting metal columns.
Books can only fit onto the structure face down, so that the text on each spine is correctly orientated.
The library installation is on show inside the museum's new wing, the Herta and Paul Amir Building, which we featured on Dezeen last week - see our earlier story here.
You can also find out more about design from Israel in our special feature.

Here's some more text from the Tel Aviv Museum of Art:
Chanan de Lange: Ex Libris
"Ex Libris" is a library composed of two rounded objects, capable of storing 20,000 books.
The work raises questions about the manner and "ease" of a book's placement on a shelf and about the visitor/user's progress through the space defined by the library.
The book accompanying the exhibition presents numerous libraries designed by De Lange throughout the years – private and public libraries, some of which are functional and some display objects – and points out the material, formal and technological connections between them.
