As far as I can make out it's a reprint of a 19th century maths text book. Does the program that sends these things have no sense?

It's a programme. It works, as far as I can tell, on the simple idea that if one person purchases an item they will be interested in any item ever purchased by by someone else who purchased that item....

I thought categories came into it too, but see the other comment and my reply, which I think solve the mystery.

I'm not sure about that, since if I happen to say I own a specific film it promptly asks me if I want soundtracks or games (neither of which I have ever purchased) not just for that film but a lot of other films, some of which are out of left field.
