Google any portion of the title of (eg the newspaper article) what you are looking for.
If the page is showing as deleted...instead of clicking the Google link..click on the 'Cached' link
This will take you to the page as it appeared before updates.
TIP: When searching for old MF threads..add 'Mirror forums' to the search..'View topic'..or any buzzwords specific to that thread.
Adding the member name of those that posted in that thread helps too
For Newspapers..add the name of the newspaper in the search.
