The Frankfurt Book Fair is mostly about buying and selling the rights to books, and about publishers and literary agents connecting with other publishers and literary agents in the hope that they together will sell more books. Often this connecting involves food and alcohol, which is where Richard Charkin ( a British publishing executive who has held numerous high ranking positions in the industry including Chief Executive of Macmillan Publishers Limited and Executive Director of Bloomsbury, and who currently manages Mensch Publishing, a company he founded in 2018 and serves on the International Advisory Board of the Frankfurt Book Fair) Richard Charkin and I show up with a special episode of The Biblio File.    We met at Bistro Salvatore (a great, reasonably priced restaurant located near the Main) for a slightly moist, frequently jovial conversation initially about David Whitaker (who died on 4th August of this year) and the ISBN, and then about, among other things, truth, copyright, the physical shape of books, Canadian government support for authors, and the fact that Richard has attended the Fair almost fifty times.
