The h-index can be fractionalized to take into account multiple authorship. We discuss the problems associated with fractionalization and point out that only one method satisfies the count conservation rule. We illustrate with examples taking care to use a subtle interpretation based on specific impact and not citations.

Abstract


The h-index can be fractionalized to take into account multiple authorship. We discuss the problems associated with fractionalization and point out that only one method satisfies the count conservation rule. We illustrate with examples taking care to use a subtle interpretation based on specific impact and not citations.
