Onenote is a note-taking software from MS. It organizes information in the form of Books->chapters->Pages. I use it to organize meeting notes, Research articles collection and articles I write. It intergrate with internet browers so that you can easy clip articles from web to Onenote. It certainly does a lot more and very easy to use, takes 30 min to learn the basics.
Here is the link to purchase a OEM CD, about $30.
