Yahoo! Finance offers research reports available for purchase from more than 300 brokerage and independent research firms.

You can access reports throughout the Yahoo! Finance site in one of two ways. Click the "Reports" link that appears in the "More Info" column on quote result pages, or use the Report Screener.

Yahoo! Finance offers documents in various formats, including HTML, text, and PDF. The majority of research reports are delivered in PDF format and require Adobe Acrobat to view.

If you buy a research report, you can save it on your personal computer or Yahoo! Briefcase, and it's yours forever. However, you only have web access to the report for 24 hours.
