Since 2005 Berlin has a new architectural landmark: the Philological Library of Freie Universität Berlin, designed by the renowned British architect Lord Norman Foster. The new Philological Library offers scholars and students modern working places: 650 wireless internet-accessible reading places on 5 levels including 100 Internet research terminals and 14 workstations. An innovative environmental concept based on natural ventilation and heat recovery reduces energy use in the new building. The Philological Library is a reference library with mainly open stacks, containing approx. 700,000 books and 800 journal subscriptions. Through its various events and exhibitions, the new library provides a public space for exchange, discussion, and information.
