I would like to export a batch of citations (~400) that we are using to a zotero rdf and give it to a co-author, who is just starting to use zotero. I don't have any tags for the citations being used in this paper. I'm wondering if there's any way to use the word plugin to communicate to my zotero database which citations I'm using in the document, so that I can select them all at once in zotero and export that to an rdf. I know that if I use "edit bibliography" in the word plugin, I can see all the citations in the paper there - is there a way to tell zotero to select those citations in my database?
