What's novel about A9, which first launched with fewer features in April, isn't the search results, which Google provides under a licensing agreement. It's the personalized extras and the unusual way results are displayed in columns that users can rearrange and redesign to their liking.

A9 may appeal the most to Webaholics who visit a ton of sites and do exhaustive research online. In addition to providing an easy way to manage bookmarks, A9 lets people run a single query and see matching information from multiple sources, including a dictionary and encyclopedia from GuruNet, Amazon's "search the book" database of full-text book pages and Web images from Google.
