And in other news: 50 percent of Canadian readers lie about how many books they've read over the course of the year.

Sorry, but I'm having a hard time believing that most Canadians who've read a book in the past year read on average 20 books, that's almost two a month. That's about my rate and I've got deadlines to meet. This is a country that is provincially book-ended with literacy - BC clocked in at an astounding 33 titles per year with Atlantic Canada (didn't know there was a province called "Atlantic Canada") registering a mere 22 in second place. As a Quebecois I hang my head in shame. We're apparently too busy listening to the latest Celine Dion album(s) to read books.
