The Andrew W. Mellon Foundation has funded the MESUR project at the Digital Library Research and Prototyping Team of the Los Alamos National Laboratory to explore the possibilities of usage-based scholarly evaluation metrics. MESUR has collected usage data from some of the world's most significant publishers, aggregators and institutions to build a reference data set of nearly one billion usage events that are semantically related to all relevant citation and bibliographic data. Preliminary investigations on the basis of this reference data set have yielded one of the most comprehensive surveys of the validity of a variety of citation- and usage-based metrics of scholarly status to date, including large-scale mappings of science. This briefing will discuss the MESUR project's general methodology and preliminary results, and demonstrate an interactive environment that enables users to explore the relationships and rankings of journals resulting from their usage.
