The libraries of the University of Oxford and its colleges are among the most splendid, but also the least-known, buildings in the city. Spanning over 800 years of architectural design and taste, nowhere else boasts such a wealth of libraries in so compact an area. While for centuries, Oxford’s libraries were repositories of knowledge in the form of manuscripts and printed books, to be consulted only by scholars, today they serve both the advancement of learning and the teaching needs of thousands of undergraduate and postgraduate students. Over the years, Oxford’s libraries attracted wealthy donors, some of whom, like John Radcliffe, gave generously to the provision of impressive and architecturally innovative buildings to house the books. These buildings are still among the most impressive features of Oxford’s architectural landscape, helping to define its visual identity. Architectural styles range from medieval wooden stalls to the asymmetrical stainless steel and glass of the twenty-first century, and notable architects include Sir Christopher Wren, Nicholas Hawksmoor, Sir Giles Gilbert Scott, Sir Edwin Lutyens, Arne Jacobsen and Zaha Hadid. With exquisite, specially commissioned photography, this profusely illustrated book invites readers through the doors of over fifty beautiful and iconic libraries, revealing how they are steeped in history, learning and cultural change.
