Suppose, for example, that you are on a corporate team researching wind power. If you did a Web search and found relevant Web pages on wind power, you would click on a bookmarking button on a social bookmarking site and create a tag identifying each Web document you found to link it to wind power. By clicking on the “tags” button at the social networking site, you would be able to see a list of all the tags you created and select the documents you need.
