NL book stacks
The NL collections are kept in two underground book stacks – currently more than 5,6 million items are kept in 63'000 linear metres of shelves.
The book stacks are not accessible to the public.
Each week between 5'000 and 6'000 items enter and leave the stacks.
The annual growth is around 1'300 linear metres, which corresponds to an increase of about 70'000 items.
