abstracts, reviews, or bibliographies, and whether it is itself ab
stracted in any other publication. Another publication worth
mentioning is the 'Directory of Periodicals published by International
Organisations'published by the Union of International Associations
with assistance from UNESCO. The second edition (1959) describes
1340 periodicals of which 292 are issued by intergovernmental
organisations, and 1048 by international nongovernment organi
sations. The term 'periodical' has been interpreted in the widest
possible sense to include all organisations which produce in one form
or another, magazines, bulletins, yearbooks, reports, etc. which
have a certain degree of continuity and regularity. The entries are
arranged according to the UDC-scheme. The index consists of the
names of organisations in English and French, and the titles of the
periodicals.

2.1 United Nations
2.1.1 Three agencies of the United Nations are of importance
to surveyorsthe Food and Agriculture Organisation (FAO),
the Economic and Social Council (ECOSOC), and the United
Nations Educational, Scientific and Cultural Organisation
(UNESCO). The aims of UNESCO are to contribute to peace
and security by promoting collaboration among nations through
education, science and culture, in order to further universal respect
for justice, for the rule of law, and for human rights and fundamental
freedom; to give fresh impulse to popular education and to the
spread of culture; to maintain, increase and diffuse knowledge; to
encourage cooperation among nations in all branches of intellectual
activity; and to initiate methods of international cooperation
calculated to give people of all countries access to printed and
published material produced in any of them. UNESCO encourages
international scientific cooperation by organising meetings for
scientists, assisting the activities of international scientific orga
nisations, and promoting the exchange of scientific information,
in the social sciences, it endeavours to apply scientific knowledge
to relations between peoples at both the national and international
levels. Its efforts in documentation and statistics contribute sig
nificantly to the work of social scientists. It assists the development
of museums and libraries, studies obstacles to the free flow of
information and takes the initiative in recommending international
agreements designed to eliminate such obstacles. UNESCO has
established consultative committees to advise on the development
of international collaboration in particular fields: there is an
international advisory committee on bibliography, documentation
and terminology. It is responsible for the publication each year of a
substantial amount of information on subjects relevant to its ob
jectives. These include more than a dozen periodicals and a number
