Have you used the British Library? If you haven’t but are interested in going there and (to quote them) exploring the world’s knowledge these videos will give you tips before you go (so it is a little less scary).
It is a great resource for researchers, staff and dissertation students.
1. Registering with the library
2. Using the Reading Rooms
There are a few rules about using them so this is a great video so you know what to do before you go.
3. Exploring the Collections – Researcher
4. Exploring the Collections – Designer
Even if you don’t want to use it I’d recommend visiting the permanent Treasures of the British Library exhibition (see Jane Austen’s writing desk, The Magna Carta and Gutenberg Bible or any of their temporary ones.
