Zotero standalone field chooser
In Zotero standalone one can view one's library with a number of fields (e.g. Title, Creator, Series, etc.) . The "Series Number" does not appear to be an available choice and should be added (actually any Zotero field should be an available choice).
@Dan -- do you have an opinion on that? It's clearly a field people may want to sort under when looking at large publication series.
