As this essay suggests, the effects of (and motivations for) physical book piracy can seem complex -- access and affordability for the poorest of the poor, increased audience for writers -- but the bottom line remains intellectual property is being trespassed upon and abused.
Meanwhile over here in the digital world, book authors and publishers are trying to figure out how to secure their "treasure" while watching what appears to be an advancing fleet of pirate vessels. IP law-guy, Barry Sookman points us to a recent study showing what appears to be an epidemic of online book piracy. The study was conducted by an online piracy monitor called Attributor, and it estimates that piracy represents approximately 10% of current U.S book sales, or roughly $3 billion (USD).
Consider the potential effects for Canadian writers and publishers worldwide. According to a recent Hill Strategies analysis of Statistics Canada data, our current international trade in homegrown books is approximately $395 million. We are currently experiencing a book trade deficit of approximately $1 billion.
BTW, books, magazines and other printed materials appear to be the clear leaders in terms of Canadian cultural exports (and imports) outstripping even film and video. Granted, video games stats were not collected.
