Ever need to track down an old newspaper clipping? Until recently, you'd have to head into the library's microfiche section and dig through boxes of film. Now, it's potentially as easy as heading over to Google's recently relaunched and easier-to-search news archive.
On the main news archive page you'll find hundreds of newspapers organised by title. You can search within the paper, look through other news sources, or just check out issues from specific dates.
There's no evident Australian newspapers on the site: for that, you're better off heading to the National Library's excellent Trove archive.
