Government Documents - United Nations Collection: UN Document Numbers

About UN Document Numbers and other Call Numbers

The United Nations Collection uses the UN Documents symbols and sales numbers to classify the UN documents.  Understanding how UN document numbers and UN sales numbers work will help users locate items on the shelves as well as search databases such as AccessUN, UNBISnet, and the Official Document System (ODS).

There is also a separate in-house arrangement for UN periodicals and an in-house classification system for publications issued by the UN specialized agencies.  In some cases, it is difficult to differentiate the UN symboled document numbers from the call numbers for the specialized agencies, so see a staff member for assistance in locating the item.

Quick Guide

UN Document symbols:  the documents and publications are arranged alphabetically by the series symbol, then numerically by the individual document number. (To understand the structure of UN Document symbols see next box: Detailed Explanations and Tutorials on UN Document Numbers)
