If you will look to the left side of the screen you will see what the computer folks calls the Navigation Pane. To the left of some of the words are some gray triangles. If the triangle is pointing to the right then it means that there are some more items below it and not showing. If you click on the triangle it will point down and you will see some more words on your screen. To reduce the words you see in the Navigation Pane, click on any of the triangles pointing down and it will collapse the words below it and point to the right.

So, if you see all the September dates showing, if you click the triangle to the left of the words September 2013 it will remove from view all the September issues, but they will show up again if you click the triangle to the left of September 2013 again.
