When was this book last read? How popular is it across the world? How many copies of this book exist? For The Secret Lives of Books, Guerilla Dance Project and Tom Mitchell of UWE Bristol joined forces with the Library of Birmingham to celebrate the physical book as the centrepiece of information exchange. Transforming a quiet workspace into a beautiful interactive platform, their experience visualised the unexploited data sets of our public libraries, rewarding bookish curiosity with unexpected connections.
