Curated illustrations of the architectural design and history of the most beautiful libraries in Oxford and a close look at the artistic prowess of the architects responsible. The libraries of the colleges and the University of Oxford are among the finest, but also among the least-known, buildings in the city. Ranging in date from the thirteenth to the twenty-first centuries, they embody successive changes in internal design and architectural taste. Libraries were originally established as repositories of knowledge in the form of manuscripts and printed books, and until fairly recently, they were used only by scholars. Over time, the University’s libraries, and those of the constituent colleges, attracted wealthy donors, some of whom, like John Radcliffe, gave generously to the provision of impressive and architecturally innovative buildings in which 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 concrete and glass of twentieth-century Brutalism, and notable architects include Sir Christopher Wren, Nicholas Hawksmoor, Sir Giles Gilbert Scott, James Gibbs, Sir Edwin Lutyens, and Arne Jacobsen. With 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.
