Hi there

I would like to know what I can correctly call myself.

The book contains 101 chapters, each written by a different author. Some of the authors are "big names" such as Jack Canfield and John Gray. I have been calling myself a contributing author but I notice several of the authors are describing themselves as co-authors. Of course being a co-author sounds MUCH more impressive but I don't want to mislead people.

So... what do you think (the link below in my signature is to the book I am talking about)
