Instapaper is a free service that allows you to save web pages that you find interesting, but don't have time to read now, for later.
Instapaper gives you a "Read Later" bookmark that you just click. Then you come back to the site later to read them or print them out, or read on your iPhone/iPad/iPod Touch or your Kindle.
This is a great tool for busy educators to save web sites and articles for when you have time to read them.
