peterwayner writes "Six of the top ten links on a Google search for one of my books point to a pirate site when I type in 'wayner data compression textbook.' Others search strings actually locate pages that are selling legit copies including digital editions for the Kindle. I've started looking around for suggestions. Any thoughts from the Slashdot crowd? The free copies aren't boosting sales for my books. Do I (1) get another job, (2) sue people, or (3) invent some magic spell? Is society going to be able to support people who synthesize knowledge or will we need to rely on the Wikipedia for everything? I'm open to suggestions."
