Cambridge University Library is celebrating its 600th anniversary this year with a physical and online exhibition called “Lines of Thought: Discoveries That Changed the World”. The historic library has grown from a small collection of manuscripts kept in a wooden chest into one of the world’s greatest libraries with more than eight million items, ranging from inscriptions on ox bones and turtle shells, illuminated manuscripts, and early printed books, to ebooks and digital archives.

The exhibition in Cambridge runs until September 30, 2016, but if you can’t make it in person you can view it here online.
