"Google Scholar quietly launched a new service, Google Scholar Metrics, earlier this month. Google Scholar Metrics allows users to browse a ranked list of publications in a variety of disciplines, sorted according to their h-indices."
"Google Scholar envisions that authors will use the service to “consider where to publish their latest article,” and also discover resources outside of their primary field of study. (As interdisciplinary research continues to grow, the latter functionality will likely become increasingly valuable.) Resources are also categorized by language, and journals may also be searched for using non-English terms (e.g. “salud”)—albeit on a limited basis.
Since the service launched, I’ve been thinking a lot about what Google Scholar Metrics can do for librarians. The first—and most obvious—possibility is that subject librarians can use it in a way similar to authors, in order to become familiar with new resources outside of their primary area of focus. They also might use it to supplement their calculation of the potential value of new journals (and not to mention that of traditional resources), before making purchasing decisions.
