Diigo provides a browser add-on that can really improve your research productivity. As you read on the web, instead of just bookmarking, you can highlight portions of web pages that are of particular interest to you. You can also attach sticky notes to specific parts of web pages. Unlike most other web “highlighters” that merely clip, Diigo highlights and sticky notes are persistent in the sense that whenever you return to the original web page, you will see your highlights and sticky notes superimposed on the original page, just what you would expect if you highlighted or wrote on a book!
