The Library has major collections of publications from governments and intergovernmental organisations, including many statistical publications.
While UK government publications are naturally the most strongly represented, this collection does not end there. For other countries the Library aims to acquire central government publications containing social or economic data, or illustrating the processes of government and public administration. A special deposit agreement, dating from 1903, ensures an extensive collection of US federal government publications.
Since 1946 the Library has been a United Nations depository library, providing a comprehensive collection of UN publications and documents. Many other organisations are significantly represented, including OECD (Organization for Economic Co-operation and Development), ILO (International labour Organization), OAS (Organization of American States) and GATT/WTO (General Agreements on Tariffs and Trade / World Trade Organization). As a European Documentation Centre, the Library has received publications from the European Community since 1964.
