Joachim Schöpfel Chérifa Boukacem Zeghmouri Conference report Usage assessment the French touch International Symposium: Academic Online Resources: Assessment and Usage Lille France November In the heart of Europe at only hour mins from St Pancras hour from Paris and mins from Brussels Lille hosted the first international conference on digital usage assessment in France LIS professionals and scientists from five continents met for two days on the scientific campus of the Lille University and discussed usage related approaches to academic digital libraries Usage assessment in France Since French information experts and academic librarians developed an intensive research activity to understand and accompany the uptake and usage of scientific digital resources Most of the research is linked to the academic big deals from the COUPERIN consortium and to the CNRS scientific information portals The scientific information centre INIST made available on its website a French version of the COUNTER Code of Practice and created a service on usage statistics The National Research Agency ANR funded a year research project EPEF on usage of journals databases and ebooks by the French academic communities based on a unique partnership between international publishers academic libraries and experts from Lille Nancy and Paris Lille University supports a nationwide study on the development and usage of French open archives and hosted in the first French symposium on usage assessment The event is the message The first message of the Lille conference is unambiguous: usage assessment is a hot topic for the whole value chain of the scientific information market This market is fundamentally international and so is research on usage Half of the speakers sponsors and members of the program committee came from other countries than France The conference language was a muddle up of French and English but as all participants shared similar experiences with digital resources no problems of understanding occurred Scientists and ...
