If you are new to social bookmarking, you can think of it as a cross between a web-based filing cabinet and a bulletin board. Social bookmarking tags a website that interests you for later use. You may already bookmark sites in your web browser, but social bookmarking saves them to the web instead of your browser.
Besides sharing your own bookmarks, you can also see what others have tagged or examine "tags" by category or popularity.
And because your bookmarks are web-based, you can get to them from any computer with internet access.
Because the tags on social bookmarking sites are created by real live humans instead of algorithms, searching social bookmarking sites can yield uniquely targeted and relevant results.
Consider searching social bookmarking sites in addition to using traditional databases and searches to get a broad range of perspectives on your topic.
