This is a handy way to view the evolution of a news story over days, weeks, or months. Library Journal gives a good summary of its features.
Google News Timeline is freshly available at Google Labs, and it’s eye catching for everyone – but a must-check-it-out for librarians. It is “a web application that organizes search results chronologically. It allows users to view news and other data sources on a browsable, graphical timeline. Available data sources include recent and historical news, scanned newspapers and magazines, blog posts, sports scores, and information about various types of media, like music albums and movies.” [from the site]
It’s also searchable, and navigable in a variety of ways, with simple dragging and clicking figuring prominently in that navigation. You can look at specific dates, and you can add specific queries to the system (for finding information in a favorite source over time, for example). My search for “john cusack movies” brought up a timeline of his films, ranging back as far as 1985’s The Sure Thing up to 2012 (due out in July), graphically showing the range of material he’s been in (and making me wish for about 3 sequels to Grosse Pointe Blank – it was just that good).
