Just an aside on the design rather than the content:

I was wondering for a while about the greenish and yellow bars on the margins of the page, but I'm pretty sure that those are padding to make the document work well on both US letter paper and A4 at the same time! The text area is A4 proportions, so if it were printed, zoomed to size on that paper, the sidebars would simply disappear.

No doubt this is a common technique that I'm just noticing for the first time.
