I'm trying to figure out what are all of the possible MARC fields displayed at the top of the full record display as well as the description tab. I have two questions.

1. Are these configurable?
2. Where can I get a full list of all of the possibilities?

I've already parsed templates/RecordTab/description.phtml for the description tab (so I think I have that) however, I'm currently looking at the following files.


I'm not sure under what condition each of these is executed or if this is even the best way to get the information I'm after. Does anybody know?

As always, thanks for your time!
