Yahoo now offers a search interface for paid subscription content from:
FT.com (60 days)
New England Journal of Medicine
Wall Street Journal
In order to view the actual content of the search results you need to be subscribed to the individual content sources. However it is convenient for searching multiple subscription content sources at the same time. via Reuters
Nice feature by Yahoo but there’s a business library in the Twin Cities called the JJ Hill Library that has offered a fantastic online search service for many different subscription services for the past 2+ years.
