On the SCM main menu, use the options available in the submenu of the View command to either show all baselines in the Baseline Library or only the latest versions of the baselines in the library.
The submenu of the View command also provides options to view the baseline change log, and to hide the Baseline Library pane and the Action pane. To toggle the display of these two panes, on the main menu, click View, and then click Show/Hide Baseline Library (Ctrl+L) or Show/Hide Action Pane (Ctrl+R).
