Digital library is commonly seen as a type of information retrieval system which stores and accesses digital content remotely via computer networks. However, the vision of digital libraries is not limited to technology or management, but user experience. This book is an attempt to share the practical experiences of solutions to the operation of digital libraries. To indicate interdisciplinary routes towards successful applications, the chapters in this book explore the implication of digital libraries from the perspectives of design, operation, and promotion. Without common agreement on a broadly accepted model of digital libraries, authors from diverse fields seek to develop theories and empirical investigations to advance one's understanding of digital libraries. This book contains the following chapters: (1) Convergence and Divergence Among Digital Libraries and the Publishing Industry (Terence K. Huwe); (2) Integrated Information Access Technology for Digital Libraries: Access across Languages, Periods, and Cultures (Biligsaikhan Batjargal, Garmaabazar Khaltarkhuu, Fuminori Kimura and Akira Maeda); (3) Bringing the Digital Library Design into the Realm of Enterprise Architecture (A. Abrizah and A.N. Zainab); (4) Integrating Disparate Digital Libraries using the WASSIT Mediation Framework (Faouzia Wadjinny, Imane Zaoui, Ahmed Moujane and Dalila Chiadmi); (5) Sorting Search Results of Literature Digital Libraries: Recent Developments and Future Research Directions (Sulieman Bani-Ahmad); (6) Exploring Digital Libraries through Visual Interfaces (Beomjin Kim, Jon Scott and SeungEun Kim); (7) Automating the Maintenance of Greenstone Collections (Wendy Osborn, Steve Fox, David Bainbridge and Ian H.Witten); (8) Security and Digital Libraries (Edward Fox and Noha ElSherbiny); (9) Institutional Repositories: Facilitating Structure, Collaborations, Scholarly Communications, and Institutional Visibility (Liauw Toong Tjiek (Aditya Nugraha); (10) Developing and Using a Guide to Assess Learning Resource Quality in Educational Digital Libraries (Heather Leary, Sarah Giersch, Andrew Walker and Mimi Recker); (11) Multitasking Made Easy: Supporting Academic Writing in Digital Libraries with an Ambient Search System (Anatoliy Gruzd and Michael B Twidale); and (12) Integrating Digital Libraries with Instruction: Design and Promotion of Educational Applications (Kuo Hung Huang).
