Google Notebook makes web research of all kinds – from planning a vacation to researching a school paper to buying a car – easier and more efficient by enabling you to clip and gather information even while you're browsing the web.
And since Google Notebook lives in your browser, you won't be left with a scattered collection of notes, Word docs, and browser bookmarks to sort through; all your web findings will be gathering into one organized, easy accessible location that you can access from any computer.
首先要安装扩展，支持Firefox1.5及IE 6，Linux也可以用。装完扩展，右下角会出现OpenNotebook的功能，点出是一个小窗口，可以自己写；也可以在网页上选中文字后右键，选Note This。同Gmail的编辑一样，网页上能选中的都可以收录进来，包括图片和链接。但似乎少一个“Note this page”的功能。
Notebook主页面上可以整多个笔记本，一个笔记本可以打上Section header，然后再加内容时就出现在这个section下面了。
现在每一个搜索结果的后面也会有Note this的链接，点击也可以直接加入，不过并不包括该网页的内容，而只是搜索结果显示的那些，相当于是一个bookmark的功能。
