Back in September 2009, The Public Library of Science (PLoS), already the publisher of the #1 ISI impact factor journal for Biochemistry and Molecular Biology, announced that that all seven PLoS journals would provide online usage data for published articles. With this addition, the suite of metrics on PLoS articles now includes measures of:
- online usage
- citations from the scholarly literature
- social bookmarks
- blog coverage
- ‘Star’ ratings
Here are some reports from the blog universe on the availability of this usage data.
- Lars Juhl Jenson constructed a normalized set of article level metrics, calculated coefficients among the reduced set of article level metrics, and judged the effect of his normalization.
- Heather Morrison used the opportunity presented by the PLoS news to call for a means of combining statistics from institutional and disciplinary repositories with publishers’ statistics.
- Michelle Kraft echoed those tuned-in to social networks to emphasize that ” Twitter, blogs, and social bookmarks are naturally going to be quicker than traditional communication methods employed within research“.
