Needs Expanded Author Types
There is no author type provision for "compiler" and the software doesn't easily address institutional authors . . . it assumes a last name, first name for all authors.
This is an old discussion that has not been active in a long time. Before commenting here, you should strongly consider starting a new discussion instead. If you think the content of this discussion is still relevant, you can link to it from your new discussion.
You can cite institutional authors by clicking on the field to the right of the author for single field mode.
@ Adam Smith - I would refer you to the Chicago Manual of Style for the use of compiler: 15.66-67, 15.77, 15.89, 15.96-100, 16.28-29, 16.46-48
Manuel Santos, comp., [ITALON]The Collected Works of Henritta Kahn[ITALOFF] (Boston: I. J. Filbert, 1989).
Oddly, none of the section number you cite are in the online version of the CMoS at
www.chicagomanualofstyle.org - but I do see in 15.35

that comp./comps. is indeed used.
(the French make a distinction between editor and director of publication that will make it into the next update, maybe we can tag on to that, but I'm doubtful that they actually map onto each other).
Arggem and I were referring in our comments to institutional authors which can be cited correctly as described.
