What is the difference between volume editors and series editors? I am filling out a "Consent to Publish" form and I need to fill out the Volume Editor(s) field. I tried to find out who these editors are, but all I found was the series editors and the main editor. 

For example for the Lecture Notes In Computer Science there are 12 series editors. I doubt that I should list all 12 of them. Are the volume editors a subset of series editors, or are these two concepts unrelated?
I guess this is a paper in conference proceedings that are published in the LNCS series?

Usually volume editors = programme committee chairs (or at least the PC chairs are a subset of volume editors).

Just put the names of the PC chairs; it is close enough. The series editors are something completely different (related to the entire LNCS series, not this particular volume).
