Did you see the article in The New Yorker about Art Garfunkel and his library? It seems that Garfunkel has been keeping track of what he's read over the past 40 years or so, and the list is on his website. Which is awesome.
When I first started going to John McCutcheon concerts a few years ago, I learned that he has been doing something similar. His library is just a list of what he's been reading lately, and he is known for promoting books and reading at his concerts, which is yet another thing to love about the guy.
