In 1965, the Carnegie Endowment for International Peace proposed to finance a project to open League materials to researchers. The project commenced in 1966 and concluded in 1969. The main deliverable was the creation of the archives' primary finding aid, the Répertoire Général (accessible in External Links), corresponding to the change of the League's records and documents into a proper archive.[1] Access to the archives was further defined by the official rules established in a two-page document titled "Access to League of Nations archives," published in the Secretary-General's bulletin in 1969.[5]
