Hi Courtney,
Thanks for the info.
Strange though that nobody has made this extension so far. The proper data is already available in the {{DEFAULTSORT:surname, given name}} which we should be able to keep updated.

In this case I adopted a little different approach:
1. In each Author pages I created a template for classification (say, a table with few key-value pairs as firstname, second name, country, date of birth and so on)
2. using Dynamic Page List extension I create a list of articles sorted as I like
Same approach can be useful for books too...
