United Nations: IALS Library Guides

Guide last updated by Hester Swift, June 2020

The United Nations (UN) was established in 1945 after the collapse of its forerunner, the League of Nations. Its purpose is to safeguard international peace and security, to promote justice and international law, to protect human rights and to foster cooperation between sovereign states in tackling social and economic problems worldwide. Participation is now almost universal, with 193 member states. 

The Institute of Advanced Legal Studies Library has a good collection of scholarly commentary on the work of the UN. It holds UN documents and publications where they are of legal interest, and subscribes to HeinOnline's United Nations Law Collection. IALS Library is not a UN depository: the nearest UN depository libraries are the British Library and LSE Library. 

This research guide is structured by type of source - treaties, cases, books and so on - rather than by subject; for an introduction to researching particular subjects, such as human rights, or peace and security, see the research guides produced by the UN's own Dag Hammarskjöld Library.

The UN has six principal organs, as laid down in Article 7 of its founding Charter:

• The General Assembly: a deliberative, policy-making body, in which all member states are represented. It has six main committees, the Sixth Committee being the one which deals with legal matters. The International Law Commission is a subsidiary organ of the General Assembly.

• The Security Council: the UN institution primarily responsible for maintaining international peace and security; it has five permanent members, plus ten members elected for two-year terms.

• The Economic and Social Council (ECOSOC): manages the UN's economic and social development work and draws up policy in this area; has numerous subsidiary bodies, such as the Commission on Crime Prevention and Criminal Justice and the Commission on the Status of Women.          

• The International Court of Justice: the UN's primary judicial body, sometimes known as the World Court; it issues rulings on disputes between states (who participate voluntarily) and gives advisory opinions to the UN and its specialised agencies; its structure, functions and procedures are set out in chapter XIV of the UN Charter, in the Court's Statute, in practice directions and in court rules; non-members of the UN may become parties to the ICJ, or may submit themselves to its jurisdiction  in specific cases.

• The Secretariat: this is the UN's main administrative organ, staffed by public servants who carry out the day-to-day work of the UN; it is headed by the Secretary-General.

• The Trusteeship Council: set up after the Second World War to administer various territories and oversee their transition to self-government; suspended its activities in 1994, when the last of the trust territories became independent.

As well as the six central organs, the UN has a large number of specialised agencies, programmes, offices and funds; together, the central organs and other bodies constitute what is known as the 'UN System'. The specialised agencies are bodies such as the International Labour Organization, the World Intellectual Property Organization and the International Monetary Fund, which are linked to the UN by cooperative agreements. Other entities within the UN System include the Office of the UN High Commissioner for Refugees, the United Nations Children's Fund (UNICEF) and the UN Development Programme, among many others.

The scope of this research guide is largely restricted to the core UN institutions. However, IALS Library's collections do include som material relating to parts of the wider UN System, where they are of legal interest.

Further information about the UN System can be found on the UN website.

The Charter of the United Nations is the UN's founding document, signed at San Francisco on 26 June 1945.  It has since been amended several times (UN Charter, UN website). The Statute of the International Court of Justice is annexed to the Charter and is deemed to be an integral part of it. So far the Statute has not been amended (Basic Documents, ICJ website).

The official original versions of the Charter and Statute were published in Documents of the United Nations Conference on International Organization, San Francisco, 1945, volume 15 (United Nations Information Organizations, 1945-55), which is held at IALS Library. It is also in the UN Law Collection on HeinOnline (see IALS Law Databases page). There is a free online version in the UN Digital Library.

The 1945 text of the Charter and Statute also appeared in volume 1 of the Yearbook of the United Nations, which is available on the UN website. 

The current version of the Charter, incorporating the amendments, is on the UN website. The amended text also appears in Charter of the United Nations, statute and rules of court and other documents (International Court of Justice, 2007) and Blackstone's International Law Documents (14th edn, Oxford University Press 2019), both of which are held at IALS. 

​Commentaries on the Charter and Statute
Several commentaries are held by IALS Library, including:

• Bardo Fassbender, The United Nations Charter as the Constitution of the International Community (Brill, 2009);

• A Zimmerman, C Tomuschat and K Oellers-Frahm (eds), The Statute of the International Court of Justice: a Commentary (3rd edn, Oxford University Press 2019);

• Bruno Simma (ed), The Charter of the United Nations: a Commentary, 3rd ed. (3rd edn, Oxford University Press 2012).

See Library Catalogue for other titles.

Under article 102 of the UN Charter, all treaties in which UN member states participate have to be registered with the Secretary-General, who must then publish them. The purpose of this requirement is the avoidance of secret diplomacy.

The Secretary-General also has a separate treaty function: acting as depositary for more than 560 multilateral treaties. These are either treaties of worldwide interest, or treaties drawn up under the aegis of UN regional commissions and open to their entire membership. Detailed information about the depositary function can be found in Summary of Practice of the Secretary-General as Depositary of Multilateral Treaties (United Nations,1994), available at IALS Library; 1999 reissue on UN Treaty Collection website.

The United Nations Treaty Series and League of Nations Treaty Series
Treaties registered with the Secretary-General under article 102 are published in the United Nations Treaty Series (UNTS), in the original language, with translations into English and French where necessary. However, certain types of treaty may not be published in full: see 'Regulations to give effect to article 102 of the Charter of the United Nations' (A/RES/97(I), as amended).

Treaties registered with the League of Nations were published in the League of Nations Treaty Series (LNTS).

The UNTS and LNTS are available on the UN Treaty Collection website; they are also included in HeinOnline's UN Law Collection. IALS Library holds the entire printed League of Nations Treaty Series (1920-1946), and the UN Treaty Series from volume 1 (1946) to volume 2174 (2002); both series are in the IALS Offsite Store. 

There is a substantial time-lag before a new treaty appears in the UNTS: it may appear first in the national treaty series of one of the parties, or in another publication (see IALS Public International Law research guide for more information).

The United Nations Treaty Collection (UNTC)
The UN Treaty Collection is a vast library of UN and League of Nations treaties and related information. It includes the following sources:-

• UN Treaty Series: searchable database of treaties, with status information for each treaty.

• League of Nations Treaty Series: searchable database of treaties, with status information  for each treaty.

• Multilateral Treaties Deposited with the Secretary-General (MTDSG): this database appears on the UNTC homepage under 'Status of Treaties Deposited...'.  It gives detailed information about the 560+ treaties for which the UN Secretary-General is the depositary. MTDSG used to be an annual print publication; the annual volumes are held at IALS 1967-2006 and digitised versions of them are on HeinOnline.

• Monthly Statements: online versions of Statement of Treaties and International Agreements Registered or Filed and Recorded with the Secretariat, 1946 to January 2019 (ceased publication February 2019). Lists treaties recently registered by member states, giving title, date of conclusion, date and method of entry into force; annexes cover ratifications, accessions and other treaty actions. The print edition has annual cumulative indexes in each December issue up to and including December 1997; it is held at IALS from 1978-July 2009 and is also on HeinOnline (1983 to January 2019).

Treaty indexes
The LNTS has a cumulative index. The UNTS has an index for every fifty volumes; these are not cumulative, so it is easier to look UN treaties up in the UN Treaty Collection database, or HeinOnline's UN Law Collection. 

Other indexes covering UN and League of Nations treaties include:

• FLARE Index to Treaties: free online index covering about 2,000 of the most significant multilateral treaties from the late 1600s to the early twenty-first century, plus historical bilaterals (1353 to 1815). Gives LNTS, UNTS and other citations and links to the text of the treaty, if available on the internet.
   
• Christian L. Wiktor, Multilateral Treaty Calendar: 1648-1995 (Martinus Nijhoff, c.1998). Gives UNTS, LNTS and other citations and provides status information. Held at IALS, also on HeinOnline.
   
• Peter H. Rohn, World Treaty Index, (2nd edn, ABC-Clio Information Services 1983-84). Five-volume work covering bilaterals and multilaterals from 1900 to 1980. Gives UNTS, LNTS and other citations; print edition held at IALS; there is also an internet version, which is more up-to-date, but still under development.

This section covers the International Court of Justice, the UN's principal judicial body, the Permanent Court of International Justice and the UN international criminal tribunals for Rwanda and the Former Yugoslavia; for information about other international courts and tribunals, see Dag Hammarskjöld Library's International Law research guide and IALS Library's Public International Law research guide.

Terminology
A UN 'document' is defined as a text submitted to a principal or subsidiary organ of the UN for consideration by it, as against a UN 'publication', which is material intended for the public. The many different types of document include resolutions and meeting records. For general information about UN documents, see the research guide produced by the UN's Dag Hammarskjöld Library.

Document symbols
The UN identifies its documents by a system of references called 'document symbols', consisting of letters and numbers: for example, 'A/66/L.38' or 'S/2013/140'. The construction of UN document symbols is explained in Dag Hammarskjöld Library's research guide.

UN documents online
UN documents are all available online from 1993 onwards, and many older documents have been digitised and made available online too. Further details are given below (see also this UN FAQ).

To find UN documents online, search one of these databases:-

• the UN Official Document System (ODS), best for searching by document symbol;
• the UN Digital Library - best for searching by subject.

The ODS and the Digital Library have very similar coverage of official documents, but different search facilities.

Resolutions
All General Assembly (GA) resolutions, back to 1946, are on the General Assembly website in the ODS, and in the UN Digital Library. In printed form, they appear in the annual title, Resolutions and decisions adopted by the General Assembly (formerly Resolutions adopted by the General Assembly) (United Nations, 1947 - ); this title is held at IALS and is also found on HeinOnline. In addition, IALS Library has Djonovich's compilation, United Nations resolutions: Series 1, Resolutions adopted by the General Assembly (1946-1985/86), published by Oceana. 

All Security Council (SC) resolutions, back to 1946, are on the Security Council website and also in the ODS and the UN Digital Library. They are published annually by the UN in the print title Resolutions and decisions of the Security Council; this is not held at IALS, nor is it on HeinOnline, but is available at UN depository libraries. IALS Library has older SC resolutions in the Oceana title, United Nations resolutions. Series 2, Resolutions and decisions of the Security Council, compiled by Dusan J. Djonovich.

All ECOSOC resolutions are also found in the ODS and the UN Digital Library. Economic and Social Council resolutions are on the ECOSOC website as well: individually from 2001 onwards and in annual compilations from 1946 to 2000. 

The Yearbook of the United Nations reproduces significant resolutions of the Security Council, General Assembly and Economic and Social Council. The Yearbook is on the UN website, but is not held at IALS Library.

Meeting records
UN principal organs and various other UN bodies produce either verbatim or summary records of their meetings. Verbatim meeting records have 'PV' in the document symbol and summary records have 'SR'. Official records are not published for all UN meetings, however: if no official meeting record exists, information may be available on the meetings coverage and press releases website or annual report, or in the daily Journal of the United Nations, which is on the UN website from 2003 onwards (not held at IALS).

IALS Library does not hold UN meeting records, but they are available online and/or in UN depository libraries:-

• Security Council: verbatim meeting records of Security Council meetings are available in the Official Document System and UN Digital Library, and on the Security Council website, 1946 onwards. They are part of the Security Council Official Records (SCOR), which are held in print format by UN depository libraries (not at IALS).

• General Assembly: verbatim meeting records for the GA are all in the Official Document System and Digital Library,1946 onwards; however verbatim records of GA plenary meetings have been consistently produced only from the 5th session (1950/51) onwards. Meeting records are part of the General Assembly's Official Records (GAOR), which are held in print format by UN depository libraries (not at IALS).

• General Assembly Sixth Committee (Legal): the committee produces summary records, which are available in the Official Document System and Digital Library from 1946 onwards; HeinOnline's UN Law Collection has them from 1946 to 2005, under Official Records of the General Assembly, Summary Records of the Sixth Committee; IALS Library has Sixth Committee meeting records from 1951/52 to 1975 only, under the title Summary Record of Meetings.
