With a collection that’s over 150 million strong, the British Library is one of the largest libraries in the world. That collection includes books, stamps, maps, newspapers and much, much more, so there is a serious amount of treasure to be found here (we’re talking the Magna Carta, a Leonardo da Vinci notebook, the Times first edition and Beatles manuscripts). You can work in the Reading Rooms or if you’ve got a day off, visit one of their regular exhibitions.
