The My Yahoo Reader lets you view article summaries and full text right on your My Yahoo page, when publishers have provided them. At the bottom of each article in the Reader is a link to the publisher's website. If you prefer to go directly to the publisher's site, you can turn the Reader off completely for by selecting Options, clicking My Yahoo Reader, and then clicking the Off option. You must be signed in to do this.

If you are signed out, you will still have the option to turn the My Yahoo Reader off within the article preview. You will be prompted to continue reading the article or you can select, "No thanks, turn this off."

Tip: You can open articles in a new window or new tab using the context menu (right-click or control-click in Windows; command-click on a Mac).
