Yahoo! Search Subscriptions allows users to enter the "deep web" to reach millions of access-restricted websites containing content that search engines, like the basic Yahoo! Search, do not usually turn up.
Initial content providers signed up to the pilot service include Forrester Research, New England Journal of Medicine, Consumerreports.org, thestreet.com and the technology site IEEE, as well as the FT.com and WSJ Online.
Salim Mitha, director at Yahoo! Search UK and Ireland, said: "Yahoo! Search Subscriptions is part of our vision to make Yahoo! Search the front door to content, including both the public and deep web, by working with the best content providers."
Over the coming weeks Factiva, LexisNexis, Thomson Gale and Association for Computing Machinery will be included.
