Series primarily consists of legal instruments signed between UNESCO and member states, including state agencies and corporations. Instruments include co-operation agreements, host-country agreements, funds-in-trust agreements and plans of operation. UNESCO agreements signed with local governments are also filed in this series. The series also contains agreements signed between UNESCO and international, regional or other multilateral organizations as well as all multilateral conventions and recommendations adopted by the General Conference or other intergovernmental conferences which designated UNESCO as a depository. United Nations University (UNU), University for Peace (UPEACE) and World Maritime University (WMU) agreements are filed in this series, but other agreements signed with universities, including state universities, can be found in series B. UNITWIN agreements may be filed in this series or series B. Instruments are given a reference code and registered upon receipt in the Archives and are therefore in rough chronological order.
