Thanks for the reply. Updated the OP - my areas of interest are the kinds of things that get posted about on HN, but I'd really like to broaden my horizons and learn about things like politics and economics and philosophy, anything interesting really. I'm leaving tomorrow so the only requirement is that I need to be able to get it before then. I had planned on downloading/buying stuff for this during the weeks before I leave but just never got round to it. African Fractals looks interesting though, I'll check it out. Thanks
