The International Organization of the Francophonie (Organisation Internationale de la Francophonie, OIF) which developed over the last decades of the twentieth century brings together, as of 2008, 53 State and government full members and 13 observer members, spread out over five continents. The Répertoire des bibliothèques nationales de la Francophonie, which is in its third edition (2008), presents index cards on every national library, or library fulfilling such a role, of each member or observer country. After presenting an overview of the International Organization of the Francophonie, this article looks at the creation of the national library in each country, legal deposit and national bibliography. Then, communication (websites) and international relations (membership of IFLA) are addressed. Of the 63 countries surveyed, only 9 countries do not have a national library, although the majority of these nine countries have another institution – a national documentation centre, public or parliamentary library or national archives – that normally fulfils the functions of a national library. It must be recognized that there is a large disparity between the national libraries of developed countries in Europe and North America and those in developing countries of sub-Saharan Africa, Asia and the Antilles. In some sub-Saharan African countries, the national library has only a nominal existence.
