As a sophomore / junior, I'm thinking about research more and more. I'd like to know what books in my field are the most frequently cited so I can know what average professional does. Sure, you can look up the number of citations that any particular book has, or browse the advanced section at the library or on Amazon. But having all that information at once would be great. Maybe one could pull data from Google Scholar and show the number of citations next to the book title on Amazon? Has anyone seen something like that?
