A research work of this nature is usually a product of a careful, thorough, analytical and articulate work, usually made possible not only by the intellectual input of the student but by the remarkable contributions of many intellectuals. First among these is Prof. (Mrs) V. W. Dike, the thesis supervisor, for her excellent and immeasurable contributions towards the successful completion of this work. Her accessibility and readiness to help, led to the completion of this thesis in particular and the programme in general. Her high sense of understanding, dedication, encouragement, conscientiousness and unassuming character, have endeared me to her. Indeed, Prof. Dike is a rare gem, a workaholic, highly patient and a special breed of an academician. I appreciate her greatly. The researcher also owes profound and immense gratitude to Prof. M.

He is always accessible at all times and always ready to help. Again, Prof. A. Nwosu, for her useful contributions and criticisms which helped to put the work in shape. She conscientiously read my work and gave useful suggestions. She deserves a lot of gratitude. Dr. K. O.

Some academic colleagues of the researcher – Julie Udensi, Comfort Onyeneho, Peter Umukoro, Austine Mole, Cyril Ugwu etc. whose exchange of ideas and company gave me the identity during this programme deserve to be mentioned. The researcher is indebted to all the Heads of Departments of Libr ary and Information Science and other staff in all the universities visited for data collection, for their co-operation for availing me the necessary information in my research area and gave relevant suggestions too.
