Abstract
In academic libraries, electronic resources usually dominate the expenditure, but their usage is not systematically analyzed. Usage analysis usually requires manual integration of reports from various vendors in different formats via diverse channels. This makes it difficult to evaluate the cost effectiveness. In this poster, we implemented a systematic model to aggregate heterogeneous resources for literature usage analysis in academic libraries. First, usage reports from various vendors were automatically extracted. Then, diverse semantics of usage reports were parsed and transformed into a uniform format extended from COUNTER standard. Finally, objective analysis based on usage and cost statistics was conducted. This helps automatic usage reports aggregation and evaluation of resource development policy.
