This book examines the ethical issues and dilemmas that arise in digital libraries, and the codes of conduct, professional guidelines and ethics resources used in resolving them. The book begins with an overview of classical and applied ethics, then reviews the codes of conduct of professional information societies (libraries, archivists, information technology). The book then examines issues and situations that arise in digitization and digital library management, and explores the ways established information ethics can be applied and adapted to these cases.
