Following a request by the International Law Commission, the General Assembly, in resolution 987 (X) of 3 December 1955, requested the Secretary-General to arrange for publishing an annual publication entitled Yearbook of the International Law Commission, containing the principal documents and summary records relating to each ILC session. It has since been published annually in two volumes in respect of each session
