This book constitutes the refereed proceedings of the 11th International C- ference on Asian Digital Libraries (ICADL 2008) held in Bali, Indonesia, in December 2008. The objective of this conference series is to provide a forum for presentation of high-quality research in the ?eld of digital libraries. ICADL 2008 provided an opportunity for digital libraries researchers and practitioners in the Asia Paci?c area and beyond to gather to explore ideas, exchange and share experiences, and further build the research network in this region. ICADL 2008 was a truly international event, with presenters from 21 countries. A total of 63 papers were accepted for inclusion in the proceedings: 30 full papers, 20 short papers, and extended abstracts of 13 posters. Submissions were subject to a rigorous, blind peer-review process. The research topics cover the spectrum of digital libraries, including multimedia digital libraries, usab- ity and evaluation, information retrieval, ontologies, social tagging, metadata issues, multi- and cross-language retrieval, digital preservation, scholarly p- lishing and communities, and more. Additionally, three tutorials were o?ered in association with the conference by Andreas Rauber (Vienna University of Technology), David Bainbridge (University of Waikato), and George Buchanan (Swansea University).
