If you haven't heard about this guy yet, then you need to check out Ethiopa Reads. This is a guy on the list of CNN's heroes (follow this link to vote for him being the top hero!) who's making a life's work of bringing books and reading to Ethiopa, to kids who may never have held a book before. Wow.
And the dude is a children's librarian! He left a job in the San Francisco Public Library to go back to Ethiopia and start up the ultimate bookmobile service! How much do I love that? Answer: a lot. I love it a lot.
