Bulk import a set of papers under Zotero

pietrobraione

Hello and thanks to all the people who will help me with my newbie question. I have imported a bibliography derived from a Scopus query (as a .ris file). The import went ok, but now I would like to have under Zotero a copy of all the papers that have a DOI, and that I am able to download through my university's digital library. Is there a procedure that allows to automatically import under a Zotero library the full text of all the papers in the library from their DOI? (note that the URL field will not work, as it does not point to the paper's full text).
Thanks again
Pietro
