Mediabistro‘s GalleyCat blog just posted this interesting graphic about nonfiction books everyone should read. It’s from designer David McCandless, who created it for his new book Knowledge is Beautiful. I’m a bit of a nonfiction dork, so I was interested to see some of the titles he included. What do you think about the books on this list? Which ones have you read? What did you think about them? And, is there anything that you think he left out? Let me know in comments!
