Displaying books by subject or author

We're a small publisher and would like to be able to display products by either author or subject. Is there an easy way to do this? For example, we'd like to automatically display all of an author's titles on the same page as their bio. Is there a way to say "in this block, display all the products with keyword AuthorName"? Or would we have to add those links manually every time we add a new publication? 

Thanks for any insight you can provide!
