Zotero review
A good source can be useful in two articles. Zotero lets you put the same library item in both collections, so an interview saved for one piece is still easy to find when it comes up in another.
Put the source where you’ll look for it
Give each article its own collection. An item can sit in both without creating two records. I’d tag an interview “to-read” while it waits, and add a topic tag if I expect to come back to it. The same collection can then show everything saved for one piece or just the sources I still need to read. I’d use Scrivener for the draft and its chapter notes.
Save the view you keep coming back to
A saved search can show all items with the “to-read” tag and update as you add or remove that tag. If you copy an item to a group library, its tags travel with it. Its position in your personal collections stays behind. Make a collection in the group library if the team needs to see those items together.

Anabel’s take
I’d start with a collection for the piece I’m writing and a single “to-read” tag. At the end of a long article, the view I want is the one that shows what I still need to read before I can trust the last paragraph.
