UN Documents versus UN Publications

According to the Regulations for the Control and Limitation of Documentation, the UN defines documents and publications in different ways and uses those terms to refer to specific types of materials. The following are the basic definitions, along with a general overview of the types of content that fit within each definition.

  • UN Document: Document refers to a text submitted to a principal organ or a subsidiary organ of the United Nations for consideration by it, usually in connection with items on its agenda. UN Documents typically involve all underlying material that supports official publication, including meeting records, transcripts, and other reporting.
  • UN Publication: Publication refers to any written material which is issued by or for the United Nations to the general public. UN Publications include major studies, reports, statistical compilations, the Official Records of the principal organs, and the U.N.T.S.

UN Document Classification System

Each UN document has a unique symbol at the top right of the document or on the cover page. These symbols include both letters and numbers, and having a general understanding of this classification system can aid you in researching UN documents. The symbol typically looks like the following:

Below you will find a table outlining the first component. Note that there are additional secondary components to this classification system which allow for the identification subsidiary bodies. You can learn more about those on the UN website.
