For anyone who has read Comac McCarthy's The Road, this is a must. Thank goodness for The Millions. Great literary websites like this are nigh extinct now.
Another great article is this one, an interview with an anonymous internet book pirate. I won't get too into it now, as my anti-intellectual-property rant is currently being saved for my senior thesis, but the interview strikes many of the most important points in the issue: people who pirate the most are usually the people most in love with the medium, these people are also willing to pay for nice physical copies of the same works, these sorts people contribute more to the exposure and hence, the sales, of a work than almost any other factor, and in cases where authors and publishing companies have put their works up for free downloading, such as Cory Doctorow and the Baen Free Library, they have actually experienced increases in revenue.
