On the Tips page of Statefree-Learning.org, I suggest keeping track of what you have read as a motivational tool. I do, and it is helpful. I track my progress in an excel spreadsheet. Here is a summary for the first half of calendar 2009. Only books are included, not academic articles, etc. Although it takes a lot for a book to make it onto my to-read list to begin with, inclusion on read lists does not necessarily imply recommendation.
