"Freedom to read can never be taken for granted. Even in Canada, a free country by world standards, books and magazines are banned at the border. Books are removed from the shelves in Canadian libraries, schools and bookstores every day. Free speech on the Internet is under attack. Few of these stories make headlines, but they affect the right of Canadians to decide for themselves what they choose to read."

And let's not forget who the greatest defenders of these freedoms are - LIBRARIANS!
