Common Author Metrics

Citation Count: A simple summation of the number of citations for all articles by an author.

h-index: A field/discipline-dependent metric, developed by J.E. Hirsch, that attempts to measure an individual's combined productivity and impact. For example, an author's h-index is 8, as long as at least 8 of their articles have been cited at least 8 times.

Caveats

Numbers will be inconsistent based on the database/resource you are using to calculate.
Depending on the field/discipline, it can take a some for a publication to pick up citations.
Citation counts are typically captured from published resources, so gathering citations from white papers, preprints, and other unpublished materials. might be more complicated.
