Yzoo.co.uk is an unofficial meta search engine that combines search results from top engines including Yahoo, Google and MSN. Yzoo combines the search results to give a short and concise Top 10 of hopefully the most useful web pages.
The left-hand sidebar displays the top search results from a combination of search engines. The right-hand sidebar stores and displays the latest searches carried out by Yzoo users themselves.
Very handy!
