where to change author labels for each publication type

Issue Summary

I am rather stumped, been searching for hours but simply cannot find this setting. What I would like to do is change the secondary author label for certain publication types to editor. I saw a previous post http://drupal.org/node/1084386 where it says:

You can change the label of that field for any given publication type by going to the "admin/settings/biblio/fields/type" page and clicking on "edit" for the type in question.

But how do I access those settings= in version 7 of the module?

Best,
Gerben
