I recently submitted a paper to a journal. It came back with a "revise and resubmit" recommendation and two referee reports. Both of them were quite positive. One of them suggested that I remove from the paper a certain topic and publish it separately in order to give it more visibility. The other referee and the editor did not say anything about splitting.
The referee's suggestion seems reasonable, but I am not sure how it should be done technically:
- Should I submit the two sub-papers into the "resubmit" form? (but what if the other referee does not agree to the split?)
- Does the other paper have to go again through the entire review process, including finding new reviewers?
- How much additional work does this split entail for the editorial board, the reviewer and the authors (in addition to the obvious work of writing a new paper)?
