book links

At the bottom of the left-hand column are books I recommend. They are set up as referral links to Amazon (UK). I’m not seriously expecting a useful revenue stream from this, it’s just a way to liven up the appearance of the site. The plan is to occasionally add a new title, and as books get bumped off the bottom of the page, I’ll move them to a page that will act act as an archive of all the old recommendations.
