Google has completed the purchase of 20 million digitized historical newspaper pages from PaperofRecord.com. The two have had an agreement for two years and has now concluded in a sale that was voted on by shareholders of PaperofRecord's parent company, Cold North Wind, Inc.

This should be quite an asset to Google's historical newspaper initiative, announced in September.

PaperofRecord is based in Canada and was the first to digitize the entire history of the Toronto Star. In addition to digitizing newspapers in Canada, the United States, Mexico and Europe, PaperofRecord has digitized historical documents including he Diaries of William Lyon Mackenzie King, Canada's longest serving Prime Minister.
