Google's power searching course
I am having fun this week taking Google's online power searching course.
Some of it is very familiar for anyone who does a lot of searching, but there is some mind-widening stuff in here, too. For instance, I hadn't thought about using the color filter on images to narrow down specific types of things (the black and white option, for instance, will pull out charts and graphs that tend to be in B&W).
There's also the ability to find KML data using the "filetype" filter and feed that link back into Google maps to quickly create a useful map.
I'd recommend that most journalists and journalism students take this. It's six classes with five or so lessons per class. All are on video, but you can download the documentation from Google Docs to have a hard copy.
