"With the adoption of modern technology and more importantly in this 21st century, the traditional method of service provision is astronomically becoming obsolete. Libraries are service oriented institutions charged with the responsibility of providing the right information to the right user in the right format and at the right time. In the modern information society, libraries and information centres have a new role to play. This is due to increasing use of web-based information sources and electronic services. Libraries are also being managed in a more democratic way due to flexible communication system and efficient work organisation. The transformation from the industrial revolution to information revolution by most parts of the world is a testimony that information is an essential asset for human, economic, political, social and technological developments. For effective teaching and learning, an information service centre like a library is essential that students be exposed to relevant information resources for effective understanding and exposing knowledge. This book entitled Library and Information Work therefore focuses on the challenges of modern trends in Library and Information Science. The book discusses the nature and constraints of information service provisions traditionally. This valuable work, designed specifically for library and information science professionals, covers real-world cases that combine theories of ethics and librarianship with practical, real-life scenarios. This book will assist to researchers and practitioners alike, including coverage of subjects as diverse and vital as the history of librarianship, its development as a profession, the ethics of information science, cataloging, and reference."
