The plausibility of computing the h-index of scholarly productivity and impact using reference-enhanced databases

I have linked up 4 references to articles by Peter Jacso, that focus on the pros and cons of the three largest cited-reference-enhanced databases (Google Scholar, Scopus, and Web of Science) for determining the h-index.

You can access them in the "h-index" folder on RefShare at the url below:
