Some suggestions for "Works Cited"

In the Works Cited concordance tool, I'd like to add some additional facets:

• Author
• Published Date

That would allow me to show all the times Grudem cites Carson in his Systematic Theology, for example. (And, even more usefully, allow me to compare the number of times he cites various authors.) I could also see how many times he cites books written in certain periods, too.
