Amazon.com has unveiled its own search engine, www.a9.com. Search results are drawn from Google as well as Amazon, and include search results from inside books indexed by Amazon. If you sign in with your Amazon account, you can store your search history, annotate web pages, and even see a history of web sites visited. A9.com also offers an Internet Explorer toolbar, like Google and MSN, which offers one-step searches of the Web, Amazon, the Internet Movie Database, and Google, as well as popup blocking.
