Yahoo! Launches Search Subscription Service

Yahoo! Inc., today announced the beta launch of Yahoo! Search Subscriptions  a service that enables users to search multiple online subscription content sources and the Web from a single search box. Subscription content includes for-pay news and reference Web sites. Yahoo! Search is claimed to be the first major search engine to offer the ability to search for personal subscription content found in the "deep web." The deep web includes millions of access-restricted Web sites containing content that search engines typically cannot access. The service is initially available in the U.S. and the UK.

You still however need a valid subscription to access the content.
