The Yahoo! Premium Document Search service will see the portal's users given access to various magazines, trade journals, newspapers, medical publications and academic journals, reference reports and more than 60 newswires.
Yahoo! has partnered with online research library Divine to provide users with access to 70m pages of text from more than 7,100 sources.
After doing a search, summaries of the relevant articles can be viewed for free. Then users have the option of paying for each document individually or a subscription fee of $4.95 a month, which gives access to 50 documents.
Yahoo! anticipates small business and individuals using the service, which does not affect or replace Yahoo! free search engine.
Scott Gatz, Yahoo! vice-president of search and directory, said the deal would give users "a more valuable and powerful online search experience".
Yahoo! aims to be generating 50% of its revenue from non-advertising sources by 2004. Recently, it bought jobs website Hotjobs.com and it has launched features such as paid-for auctions and car listings.
