If there are multiple Invariant Sections with the same name but different contents , make the title of each such section unique by adding at the end of it , in parentheses , the name of the original author or publisher of that section if known , or else a unique number .
If there are more than two non-combined Sections with the same name but different text , make the title of each section different by adding at the end of it , in parentheses , the name of the original author or publisher of that section if known , or else a special number that none of the others have .
