What WAS That Book?

...Used in the private White House swearing in ceremony?  It certainly wasn't one of the two Bibles used in the public ceremony.

Here's a picture of the public ceremony, on January 20, 2013.



 

 

 

 

 

 

 

You can clearly see that both Bibles are fairly thick, even though they are of different sizes.

So, my question is, what is the book that was used yesterday, shown in the picture below?



 

 

 

 

 

 

It can't be the top book; it's too big.  It doesn't really look like the book on the bottom.  There's another picture that shows it more clearly.



 

 

 

 

 

 

 

 

It looks a book inside a book cover.  What book was it?
