Should I add a serial comma when I reproduce the title of a source?
If the title displayed on the title page of your source contains a serial comma, include the comma when you reproduce the title. For example, the title displayed on the title page below contains a serial comma:
The comma is thus included when the title is reproduced:
After the Wreck, I Picked Myself Up, Spread My Wings, and Flew Away
But here is an example of a title page displaying a title with no serial comma:
So no comma appears when the title is reproduced:
The Lion, the Witch and the Wardrobe
