Hello? Is there anybody out there?

Well, it is a few years till the Internet starts getting invented, so perhaps not!

Nevertheless, by applying a little time travel technology (the formulae were borrowed from the pages of a recent Science-Fiction story; I shan’t say which one), we at the newly founded B.S.F.A. are fortunate enough to be able to broadcast in a medium that does not yet exist.

Now, when will someone invent a P.D.F. reader … ?
