A new feature has premiered on Amazon, one so potentially useful to researchers, I'm not sure they'll leave any bandwidth available for bookbuying.

When you type in an author's name as a search term in the books section, Amazon returns a list of wherever it found that name internally referenced within a book (e.g. in footnotes).

Amazing.

I mentioned William Marvel, Burnside's biographer in the post below below. Try typing in William Marvel's name. This is what you'll get.
