@owb - If you had your library open in CalibreSpy, you could open the epub from there, copy whatever from it, and paste it into into the Author Link in the already open Library manager->Manage authors dialogue.
Probably easiest to select the VL in CS and then use its "Browser" window.
And if CS isn't already running, you can run it from the command line - in fact it's better to do that - 3 line bat file
Code:
@echo on
START calibre-debug -r "CalibreSpy" -- --"D:\Calibre\Libraries\Books"
pause
