CZ:Name of subpage set?

What name do you want to use for groups of subpages about the same topic? This is a plebicite on an issue that the Council probably doesn't care about.

I am nixing several suggestions in keeping with this discussion:

Folio, for the reasons given
Locus, because I think it's too recherche
Constellation, nice image but name is too long
Compendium, ditto
Article set, because subpages in most cases aren't articles at all
Article series, ditto

That leaves us with four options.

RULES: all and only Citizens may vote. You may vote for as many options as you wish. You may also vote "NIX <your name>" and that cancels someone else's vote for that item. (This way we account for the ones that people feel strongly against.) Vote will close on Monday when the Editor-in-Chief feels like closing it.

Options are listed here alphabetically left-right.
