Birte Christensen-Dalsgaard is Deputy Director General at the Royal Library in Denmark.

She started her career in Theoretical Atomic Physics, where she got her Ph.D. in 1984. She left physics in '91 to focus on the development of multimedia learning application at UNI-C, the computing centre for research and education. Her work gradually changed towards developing applications running over high-speed network and towards digital libraries. In 2000, she took the consequence of her interest in information and generally library issues and became Head of IT Research and Development and later Director of Development at the State and University Library in Aarhus. Her role was in participating in the strategic planning and its implementation. In the last years her interest has mainly been on the role of the library in the information economy with emphasis on digital preservation and on identifying and tailoring services to specific communities.

In 2008 she moved to Copenhagen to take up a position as Deputy Director General at the Royal Library with special responsibility of developing new digital services and to foster the digitization activities. The Royal Library holds large collections of e.g. books, maps and photos and works towards ensuring that these collections become part of the digital cultural heritage.

In recent years she has started to revisit an early interest dating from the early 1980s, where she during her Ph.D. work got into close contact with the data centre at JISC in Boulder. Ease of accessing huge amounts of data greatly stimulates research and her present work addresses issues around the requirement of reuse of data in the digital age.
