Where can I see historical market news?

When I do back-testing, sometimes I want to make clear what happened in a specific day, so can you tell me:

Is there a web site on which I can find historical market news (for example, news 3 years ago)?

 

Define news..news for what? Stocks,.macro, economic, upgrades/downgrades etc.... I have all the news for stocks that are in my universe. I would start from yahoo finance.

 

Do you mean you save news to your own database?

 

Google , for example, "Zachs stock market news sep 3, 2010"

 

yeah. in .txt files

 

Thanks for you guys, the information is very helpful
