Press-releases are not the UN official documents. You will not find them in the Official Document System of the United Nations (ODS) http:// documents.un.org / . You can retrieve SG/SM/7631 from the press-releases database http:// www.un.org/apps/pressreleases / by typing that symbol in the SYMBOL window of the search page. You also must change the DATE : FROM .... TO.... on the search page.
