PSSL 73

Since (as far as we are aware) nobody else has plans to organize a meeting of the Peripatetic Seminar on Sheaves and Logic this autumn, we are proposing to hold the 73rd PSSL in Cambridge on the weekend of 4/5 November 2000. (This will also provide an opportunity for anyone who hasn't been in Cambridge recently to see our new Mathematics building.) Further details, including a registration form, will be sent out in late September/early October. Martin Hyland Peter Johnstone
