Although we cannot currently provide live events, The Centre for the Book is pleased to be able to at least offer pointers to online options for sustaining those craving a regular dose of book history to inoculate the mind.
Our first suggestion is the Canadian series, The Biblio File, presented by Nigel Beale. Beale interviews scholars, publishers and librarians about the world of books. You have to drill down a bit into his archives to see the full range, or you can search by keyword. Either way, you are guaranteed to find some interesting and very bookish interviews.
