Series editor: DIANE RASMUSSEN PENNINGTON, University of Strathclyde, UK There is a demand for technical skills in the information professions that students and practitioners must meet to be competitive in the current job market from database design to user centred design. The books in this series have been carefully conceived to help learners acquire these skills at a deep enough level for an information science audience but without the excessive technical detail that will overwhelm readers. Each title offers technical expertise that is situated in the context of the information professions.
