This is the time of year when everyone comes up with their "best books of 2013" lists. (Mine will be out soon.) The wonderful Largehearted Boy blog always publishes a master list of the lists.
Because I believe that the fate of the Internet is one of the most important civil liberties issues of our day, I particularly liked the Electronic Frontier Foundation's list. Some of the books are available as a free download. I've read one of them (the Cory Doctorow), have a couple of others on my Kindle and plan to acquire some more.
