Issued annually since 1946/47, the Yearbook is the principal reference work of the United Nations, providing a comprehensive, one-volume account of the Organization's work. It includes details of United Nations activities concerning trade, industrial development, natural resources, food, science & technology, social development, population, environment, human settlements, children & legal questions, along with information on the work of each specialized agency in the United Nations family. The Yearbook is an indispensable guide to the UN.

Topographic mapping plays a basic and important role within the extensive field of cartography. In recent years, this type of mapping has become somewhat neglected and available literature is normally restricted to details concerning the programmes of individual countries often presented in the form of monographs. Topographic maps are essential tools for use in development projects, resource exploitation, the planning of construction, infrastructure and recreation. They also give detailed illustration of the relative degrees of development of areas within a landscape and are thus unique in demonstrating the cultural status of a country. This book is the second of three volumes and gives details and examples of topographic maps from Central and South America and Africa. The information supplied for each country consists of a text, including a brief history of the development of topographic mapping, geodetic data, map scales and series, as well as extracts of maps and index sheets illustrating the present status of map coverage within that country. There is currently no other work employing the approach adopted in assembling this inventory. This work is a comprehensive and important reference and source book for information in the field of topographic mapping.
