Has anyone come across a coffee table book of concept cars that includes the Crossfire with pics? A paperback book would be fine.

 

Yes, the Crossfire is included in at least a couple books. I saw one a while ago at a Barnes and Noble but I don't know the name of the book. But here is an example of a book that includes photos of the Crossfire concept:

Car Design Yearbook 1: The Definitive Guide to New Concept and Production Cars Worldwide (Car Design Yearbook) by Stephen Newbury (Hardcover)

On Amazon you can preview and search some book listings for content and in the above book you will see there are at least 2 photos of the Crossfire (one small one is on the back cover).

I hope this helps. The Crossfire is probably detailed in a number of books, but in many cases there's no way to tell if you can't actually touch the book or search the listings.
