John Lloyd and Noel Fielding welcome satirist Craig Brown, librarian Katie Birkwood and writer George Monbiot. From 2016.

This week, the Professor of Ignorance John Lloyd and his curator Noel Fielding welcome:

* Craig Brown, critic and satirist, best known for his parodies in Private Eye. Writer for The Independent on Sunday, The Guardian and Daily Telegraph. Books include The Little Book of Chaos.

* Katie Birkwood, the rare books and special collections librarian at the Royal College of Physicians, London. Katie regularly contributes to the journal Library & Information History.

* George Monbiot, environmental journalist and campaigner. Guardian columnist and author of Captive State, The Age of Consent, Poisoned Arrows and No Man's Land.

The Museum's Guest Committee appreciate a mythical hotel from another age; a book that was stolen from the greatest library of the Tudor age; and the greatest bear that ever lived.
