The Index to Proceedings (ITP) is an invaluable series, especially useful for research on matters prior to 1979. It provides citation to the parliamentary documentation of the principal organs.
Each index has two parts:
One index has been issued for each year of the Security Council, and each session of the General Assembly, the Economic and Social Council and Trusteeship Council.
The ITPs are published for every session of the three major organs (General Assembly, ECOSOC and Security Council).
Publication of the indexes lags behind the completion of the sessions of the organs to allow for all documentation to be issued and included.
