Finding an authoritative site of first publication

I don't rely on opinion sources such as blogs unless they are from an official source such as Google or Yahoo News. These authoritative blogs are usually a source of first published news and fairly reliable as a resource. Many times, blogs will simply republish the news or excerpt information from an original source and rewrite the story or spin it in a new way. So it's always good to find the first source of publication when researching.
