What browser are you using?
For Firefox, on the menu bar, click on History. If it's not in that immediate list, you can click on Recently Closed or Show in Sidebar.
For IE, on the toolbar, there is an icon to the right of the Favorites button (at least on mine) that is a circle and has a green arrow. That is your History button. if you click on that, your history will come up in the side. You can also hover you mouse over the button and it will tell you what they are.
