General Question 

Input needed. Please follow-up on my talk page if that is more appropriate. (discussion not related specifically to this article). Ken Ham's Book Evolution Exposed magically appeared in high school library. Sadly we now have three books on evolution ... Origins ... BeHe's and now Kens. Question to which I can't seem to find the answer. Is it formally classified as a science book or is it classified as religion? Thanks and apologies for the "blog-like" intrusion.
