You don't. Well, you "shouldn't." As we've seen a hundred times over, using copy protection pisses off legitimate customers and does virtually nothing to deter those who don't want to pay for it. There are ways to watermark a PDF (easier now than in the old days, hence why we don't do it - it's processor intensive to watermark a 350 or 600 page PDF, and Adobe wanted a fortune for the means back then.) If you're so inclined, that might be worth investigating, but I haven't kept up on latest trends, as, for us, that would be "locking the barn door after the horse has already gone and eaten your children." Thus I can't recommend any specific means. Locking the document to prevent printing and such would be a HUGE pisser to many customers. You might sell a few, but word of mouth would likely ruin more future sales than the couple that you would 'lose'. Instead of looking at the glass half-empty (pirates), look at it as half-full. Once someone comes to buy something, that person is a potential repeat customer for MORE books.
