Working with United Nations documentation can be challenging. For starters, titles of documents are generic. In general, it's a good idea to have a basic sense of how the Organization is structured and its reporting system. (For example, the Commission on Human Rights reports to the Economic and Social Council, the International Law Commission to the General Assembly.) Many tools are available to help in this regard but perhaps the most useful is United Nations Documentation: Research Guide, which is an excellent starting point for neophytes but also has features for advanced researchers which enable them to further hone their skills.
