There will be a talk to promote the new edition of Subterranean City at Kensington Central Library on Thursday 16 September 6.30-8.00pm. Many years ago I worked in that library prior to going to university, I remember that the lecture theatre was impressive with a large capacity so I hope there won't be too many empty seats. Mind you, I did sell out the British Library lecture theatre in 2006.
I have also been asked to give a talk on underground London for the Stuart Low Trust in Islington. It will take place on Friday 15 October between 7.30 and 8.30. At some point I need to start organising my own events.
