The Beaver, a 90-year-old iconic Canadian history magazine, is changing its name to avoid a variety of misunderstandings. "Use of the word 'beaver' on the internet has taken on an identity that nobody could have perceived in 1920," said Deborah Morrison, president of Canada's National Historical Society. "And increasingly, if we put 'The Beaver' in a heading, we would be spam-filtered out." Effective with the April issue, the magazine will be known as Canada's History.
