General Partnership Agreement
Compilations were frequent before the days of electronic research, and these compilations are frequently published in loose-leaf format. Additionally, treaties and conventions may also be found individually.
Only some places where these treaties and agreements are republished are considered "official" and having a binding version of that agreement. So, even if you find a republished version through Google, that may not mean it is a binding replication of the text. Frequently, they are published officially online through particular websites sponsored by the international organization(s) that created the agreement.
