Jordan McCollum reports that Google Integrates Google Notebook in SERPs.

In the SERPs after selecting the 'note this' option, the message switches to 'duly noted' with an accompanying pop-up window that shows the noted message. However the 'note this' message only shows up once you have signed in to Google.

Google Notebook was created to:

• Clip useful information. You can add clippings of text, images and links from web pages to your Google Notebook without ever leaving your browser window.
• Organize your notes. You can create multiple notebooks, divide them into sections, and drag-and-drop your notes to stay organized.
• Get access from anywhere. You can access your Google Notebooks from any computer by using your Google Accounts login.
• Publish your notebook. You can share your Google Notebook with the world by making it public.
