Summary: What will the library of the future look like? In an age in which information and communication are everywhere and the boundaries between producers and consumers of information are increasingly blurred, the question of what a public library might represent is urgent. The notion of a classical library in an academic environment with a formal collection and a permanent staff is already wavering. As a typology the library enjoys a rich history as an important component of public space within the city. The Architecture of Knowledge offers new insights into this bastion of public knowledge and collective memory as well as fascinating prospects for its future. International experts present concepts of collective knowledge, the notion of public space, thoughts on the relationship between (new) media and (cultural) society, and insights into product management and reception. The result is a fascinating journey into the future of an age-old institution, obligatory reading for architects, librarians and users alike.
