However, in the past couple of days Google has announced a useful enhancement by adding some metrics for publications in GS database.
From the Google Scholar Blog
You can browse the top 100 publications in several languages, ordered by their five-year h-index and h-median metrics. You can also search for publications by words in their titles. For example, [design], [international law], [salud], and [otolaryngology]. To see which articles in a publication were cited the most and who cited them, click on its h-index number.
Scholar Metrics currently covers many (but not all) articles published between 2007 and 2011.
Additional useful information on the GS Metrics help page.
MS Academic Search
Because MS Academic Search is still new to many info pros, here are a few screenshots showing some of what’s available in terms of metrics. Many visualization tools are also available including a Citation Graph prototype that debuted at the end of 2011.
