The adjacent frame contains links to Web sites that that have been carefully selected for their relevance to the present discussion. If you click on the buttons these links will launch in a new browser window, leaving the present window intact.

The link marked "Dynamical Search" launches a Web search engine with a fixed search string. The results that it returns are dynamic because as the content of the Web changes, the links that this search returns will change in a corresponding manner. As with all keyword searches, not all links returned will necessarily be relevant; you must always employ some intelligence in using any search engine.
