• Official online sources of treaty status information

For each international organisation, it includes provisions concerning its powers and responsibilities in relation to treaties, including depositary functions, registration, publication, negotiation, signature, scrutiny, consent to be bound, implementation and compliance. They are arranged in (broadly) the following order:
