In this example there are two Oracle Help projects, Africa and Safari. Africa is the main project and the Safari table of contents is added as a remote view.
The two tables of contents each have their own tab in the navigation pane of the Oracle Help viewer. This was done by assigning the label "Safari Contents" to the Safari table of contents. (The program automatically assigns "Contents" as a default label for the Africa table of contents.) Remember, for views to merge they must have the same types, engine, and labels. In this case the two tables of contents were not assigned titles, so you can see in the Africa table of contents on the "Contents" tab there is no top-level book.
