improve the quality of a library. The quality can be perceived from the
organizational level or user level or both, but the perceptions of a library
user is most important as the quality of a library has been defined as the gap
between the expectations of the user and the services of a library. The main
objective of writing this book is to make the practicing librarians acquainted
with the various methods of measuring the quality of libraries."
