Since its foundation the UN has published a wide variety of documents and publications. These days most material is published digitally which increases availability of the documents and makes them easier to find.
In order to search for material which is only available on paper a basic knowledge of the UN organization and its bibliographical aids is required. Both are available at the Law Library.
In case material is not available at the Law Library the United Nations Regional Information Centre for Western Europe will supply support.
Both the UN and universities have compiled research guides. You may find references to these research guides.
Please note that some of the guides refer to the availability or call number of material which is not available at the Law Library of the UvA. In such a case the use of the CataloguePlus and the help of the library staff is indispensable.
