The new book market

I've signed a contract with Wipf & Stock to publish my book The Form and Power of Religion: John Wesley on Methodist Vitality, and I've created a separate page on this blog where I'll reflect on the publishing process.  One step in this process involves identifying academic journals and professional periodicals that will review the book.  I'm interested in knowing your e-sources for book reviews.  What online sites do you visit for book recommendations?
