Libraries and information centers have long served as the backbone of knowledge preservation, dissemination, and intellectual development in societies across the world. In the modern era, however, the field of Library and Information Science (LIS) has undergone profound transformation due to rapid advancements in information technology, digital communication, and evolving user needs. The traditional concept of libraries as repositories of printed materials has expanded into dynamic knowledge hubs that integrate digital resources, information systems, and innovative services. Recognizing these developments, the multi-author volume Foundations of Library and Information Science: Theory to Transformation has been developed to provide a comprehensive understanding of both the theoretical foundations and the transformative trends shaping the field today.

This book is the result of a collaborative effort by scholars, academicians, and professionals from diverse backgrounds within the discipline of Library and Information Science. Each contributing author brings valuable academic insights, practical experiences, and research perspectives that enrich the content of this volume. Through this collective endeavor, the book aims to bridge the gap between classical theories of library science and the emerging technological and social transformations that define modern information environments.

The primary objective of this book is to introduce readers to the fundamental principles, concepts, and practices that form the core of Library and Information Science, while also highlighting the evolving role of libraries in the digital age. It examines the historical development of libraries, the principles of information organization and management, and the changing responsibilities of information professionals in an increasingly knowledge-driven society. By integrating theoretical perspectives with contemporary applications, the book seeks to provide a balanced and forward-looking understanding of the discipline.

The chapters included in this volume collectively explore the essential domains of Library and Information Science. They discuss foundational concepts such as the philosophy and objectives of libraries, classification and cataloguing systems, information organization, and user services. In addition, the book addresses emerging areas including digital libraries, information retrieval systems, knowledge management, and the integration of information and communication technologies in library operations. These discussions emphasize the transformation of libraries from traditional information repositories into active centers for learning, collaboration, and digital access.

Special attention has also been given to the role of libraries in supporting education, research, and community development. In an era characterized by information abundance and rapid technological change, information professionals must possess not only technical expertise but also the ability to guide users in navigating complex information landscapes. This book highlights the evolving competencies required for librarians and information specialists, including digital literacy, information ethics, data management, and user-centered service design.

The editors sincerely hope that this book will serve as a valuable academic resource for undergraduate and postgraduate students pursuing studies in Library and Information Science. It is also intended to benefit practicing librarians, information managers, researchers, and educators who seek to understand the theoretical foundations and contemporary transformations within the field.

We would like to express our sincere appreciation to all the contributing authors whose dedication and scholarly contributions made this book possible. Their willingness to share their expertise and insights has greatly enhanced the quality and depth of this volume. We also extend our gratitude to colleagues, reviewers, and academic institutions whose encouragement and support contributed to the successful completion of this work.

While every effort has been made to ensure accuracy, clarity, and relevance, we acknowledge that the field of Library and Information Science continues to evolve rapidly. We therefore welcome constructive feedback and suggestions from readers, which will help us improve and expand future editions of this book.

It is our sincere hope that Foundations of Library and Information Science: Theory to Transformation will inspire readers to appreciate the enduring importance of libraries while embracing the innovative transformations that are shaping the future of information services.
