Highlight and Add sticky notes on webpages Instead of just bookmarking, Diigo allows you to highlight text and attach sticky notes to specific parts of web pages. 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! Archive pages forever and make them searchable, too New! When you bookmark a page to Diigo, you can choose to upload the page, even if it is dynamic or hidden behind the password protection.
