Google Notebook has been out for a while, but I just recently started using it. It’s really very handy if you want to keep track of ideas you have on a certain topic, or doing some research on a topic and want to save urls, and web content and want to access that from multiple places. Sometimes I want to save some work related links when I am surfing at home. Before I used to email them to my Gmail account, but now I save them in my Google Notebook.
As you can see it sits quietly in the bottom of the screen if you have installed the firefox extention. Then you can select a piece of the site you’re looking at, bring up the google notebook and then select add note. Then you can add some text of your own, if you want to, give it a title and you’re set ;).
So if you havent tried it out, I’d say give it a shot. It’s free anyway, so you can’t go wrong ;).
