Google Notebook was a browser application that allowed users to create online “notebooks.” In them, they could save images, link to different pages, or clip text and write notes – all while browsing the web. The notes were also shareable.
Google decided to shut down the tool in 2011. Here’s the official statement they provided on their FAQ page dedicated to Notebook:
“We loved working on Notebook, but sometimes we have to make the hard decision to focus more of our efforts on products and technologies that will yield the most benefit to users in the long run. With all the great innovations and improvements to Google Docs in the last few years, we think it’s a great replacement for Notebook.”
The final deletion was in July 2012. All notes were automatically transferred to Google Docs beforehand, so users didn’t lose their information.
