What's the H-index?
Devised by Jorge Hirsch, the H-index is the highest number of papers an author has that have each received at least that number of citations. This may be fairer than counting total papers or just high-ranked articles, and can't be self-inflated. Someone with an h-index of 10 has written 10 papers that each had at least 10 citations.
Essential Science Indicators
- Essential Science IndicatorsEssential Science Indicators (ESI) enables researchers to conduct ongoing, quantitative analyses of research performance and track trends in science. Covering a multidisciplinary selection of 8,500 journals from around the world, this in-depth analytical tool offers data for ranking authors, institutions, nations, and journals.

Beware Predatory Journals
Beall's List at ScholarlyOA.com lists publishers and journal titles that are deceptive in their publishing practices (charge author fees, do not practice peer-review, and do not "count" in promotion review). Always check with your advisor before submitting a manuscript for publication - they know the best journals.
