As Karen Pointed out, Series can have any number of rdfs:Labels to account for many of our use cases for collection labels for individual Series. Series statements seem to be more about provisioning for transcription and labels describing the sequence of membership to a Series.

I may be wrong, but... couldn’t an instance have a SeriesTitle (a not yet defined bf:Title subclass), that allows for recording both the transcribed series title/statement in an rdfs:label and title parts through MainTitles, Subtitles, PartNumbers? Using logic from title proposal I submitted on July 23rd, and the creation of a bf:SeriesTitle subclass of bf:Title, one seemingly could handle both Titles for the Series entity and transcribed Series Titles on the bf:Instance.

"series" is a bibliographic relationship between two bibliographic
resources. So work2 has what is probably a "part of" relationship with
work1. work2 also has a title, but that (to me) is not a
source-to-source relationship but the title is a descriptive element on
work2. I think these are conceptually very different. The title node
will be unique to that instance; the series node may have relationships
with many instances. Because it has a single context (one instance), the
title node can be a blank node. Because a series node is intended to be
related to more than one instance, it cannot be a blank node. For this
reason, having an emphasis on the series title doesn't facilitate
linking. Linking needs to be to a universally identified and reusable graph.

Assuming that this is a transcribed title, where/when is the title of
the series resource used? In other words, why have the series title in
two places? (If the transcribed title is different, I would consider
that an alternate title with the meaning: "title as it appears on the
piece.") And how would the individual volumes link to the series resource?
Another possibility is to have an identifier for the individual series
"part" -- often designated as "volume." A series would have parts:
<ex:seriesActaFoo> a <bf:Series> ;
<ex:hasPart> <ex:33333> ;
<ex:hasPart> <ex:44444> .
<ex:33333> a <ex:serialPart> ;
<ex:caption> "Volume" ;
<ex:enumeration> "A3" .
<bf:instance7> a <bf:Instance> ;
<ex:isSeriesPart> <ex:33333> .
It looks less intuitive, but it makes all of the connections. This
pattern could be expanded as the serial pattern, with each issue,
volume, part (and whatever) being identified and linked to each other.
It seems awkward, but in essence that's what the MARC holdings format
does with the serial pattern.
Note that "volume 3" of serialA will have a unique identifier that only
identifies volume 3 of serialA, not all "volume 3"s of all serials. The
URI will identifier the resource, not the caption.
