Select a category at the top and the index will appear on the left.  Click one of those links and that site will load in this frame.

Some news sources on the right are subscription papers such as the WSJ or registered services like the NYTimes.  All links on the right (on this page) and some in the table to the left will open a new window.  Close that window to return here.  Several links may be opened simultaneously by right clicking and selecting "open in a new window".
