Apparently doesn't take all data into account. Maybe it's only for the US. I tried a few researchers and none were found.

Nice! This is very interesting as a research metric. For me though, this worked out real well as literature research tool as I was able to track concept provenance and citations quickly.

I recommend you try this excellent visual tool to see how your favorite scientist measures up. The tool leverages a combination of bibliometrics and graphic design to give superb, easily-understood evaluations.

Tenure application reviewers and employers will find this especially useful.

This is a nice and user-friendly portal for the computation of citation metrics. I am not aware of other platforms with such a complete list of indexes. Something I particularly like is the fact that users may contribute to define the fields of the authors themselves, by inputting tags, which could lead to a more sound classification of disciplines in the long run.

This is a really nice and useful tool for scientific evaluation purposes. Scholarometer allows the computation of several indexes (h-index, g-index, etc.) and combines this completeness with a friendly graphical interface.
In my opinion, the main novelty of Scholarometer is the possibility to classify scientists in disciplines or topics and calculate, on the basis of these divisions, relative bibliometric indicators.
I definitely recommend it.

It is really a useful tool, especially for our academic professionals. You can use it to have a fast review of one's publications in a certain field, and do many other things. New measures are included, and visualized.

The interface is quite neat, and well-designed.

Their website has other useful integrated information, worthy of being visited.

This tool is great if you're interested in accessing metadata about scholarly publications -- either if you're doing scholarly research about impact factors, or if you're simply curious about your own. Right now the tool doesn't have a ton of metadata in its database, but it seems to be getting better as more and more people are using it and entering tags.
