Some conferences select articles for publication in a journal. In my CV, I have a section "Peer-reviewed journal" and another section "Conference". Where should I put such articles?
- Only in "Peer-reviewed journal": why not, but then the conference contribution will be missing
- In both sections: it is factually true, but in way, artificially, increases the list.
A similar question has been asked  but I understand there is a difference here: only the best conference submissions are selected for publication in a journal. It is not an automatic.
Edit Requested clarifications:
- Field is mechanical engineering, where journals are more important than conference (generally).
- The conferences have their own proceedings, plus a few papers are selected for an independent publication in a journal (that has somehow partnered with the conference).
