This pamphlet is designed to show why there are many advantages in a harmonized approach to the training of archivists, librarians, and specialists in information science and what these advantages are. Following introductory discussions of the concept of harmonization, a brief history traces Unesco's role in training information professionals in collaboration with non-governmental international organizations such as the International Council on Archives (ICA), the International Federation for Information and Documentation (FID), and the International Federation of Library Associations and Institutions (IFLA). In addition, the advantages of harmonization of training for government authorities, professional schools, and professional associations are discussed and summarized; and 10 areas are identified as appropriate for a harmonized approach to teaching: (1) the notion of information; (2) information policies; (3) systems analysis; (4) administration and management; (5) user studies; (6) documentary analysis; (7) exploitation of information sources; (8) conservation; (9) technology; and (10) research methods.
