Within an INGO secretariat there may be little general awareness of the INGOs, or IGOs, to which the organization is linked. Responsibility for such linkages may be limited to one person who may well treat such linkages as a private domain, especially when the number of such linkages makes the overall situation somewhat difficult to grasp. Amongst the membership of a national NGO which is a member of an INGO there also tends to be little awareness of the INGO activity, particularly when the NGO is a member of more than one INGO. Within the national NGO, responsibility for such linkages also may be limited to one person, so that there will be little awareness of its significance. There is even a tendency for some national-level leaders to monopolize such contacts, or to fail to relate international cooperation to the activities and problems of rank and file members.
