Attached are some files I've been collecting on the topic.  I'll send others in subsequent posts.  (You may not find them all 'worthwhile', but I can't invest the time to sort through them and guess what ones folks might find relevant.)

And, adding to Jennifer's reference to the Denver Post article, see this post on our series blog, which itself includes a link to another of our blog posts, which itself includes three separate links (to two newspaper articles and one scholarly journal article)-- phew!

Enjoy whiling away the hours in the rabbit hole they call the internet.
