Curious Amazon Result

Following up on a blog link, I came across this book:
The Truth about Conservative Christians: What They Think and What They Believe

The weird thing is that the top book to pair with this in the "Better Together" selections is Cite Right: A Quick Guide to Citation Styles--MLA, APA, Chicago, the Sciences, Professions, and More (Chicago Guides to Writing, Editing, and Publishing).

Say what? Are people who are especially interested about what Christians believe also extremely concerned about citation styles?
