Does the 'Civil War: Deluxe Collection' contain all the "Civil War" books?

I'm assuming you are talking about this book since you initially said Marvel's Civil War graphic novel. If that is the book you are referencing, then it contains all issues, #1-7, of the Marvel Civil War Comic Event. There are however various comics that tie into the story line and a sequel series, Marvel Civil War II.

All that being said, I own a copy of the book I linked and it seemed to me to be a complete story in itself.
