Publishing houses using Endnote

Has anyone figured out the best way to use Endnote as a publisher?

We edit Word documents and then send them back to the author and then the authors need to add or delete references at this stage. Currently, we use the travelling library, but don’t make any changes to it until the Word document comes back from the author because otherwise the author’s library would override any changes we have made. We’d ideally like to make changes to the references at the editing stage and then send the Word document back to the author.

Any suggestions on the best workflow for this?
