Google has started ranking journals!
Through its new service called '*Google Scholar Metrics*' currently it
cover articles *published between 2007 and 2011*, both inclusive. The
metrics are based on citations from *all articles* that were indexed in
Google Scholar as of *April 1st, 2012*. This also includes citations from
articles that are not themselves covered by Scholar Metrics.
To know which are the top 20 journals in a particular subject area just
type the subject. For example; Economics, Statistics, Mathematics etc using
the following URL address. Once you get Google Scholar search box replace
