  A variety of bibliometric measures have been proposed to quantify the impact
of researchers and their work. The h-index is a notable and widely-used example
which aims to improve over simple metrics such as raw counts of papers or
citations. However, a limitation of this measure is that it considers authors
in isolation and does not account for contributions through a collaborative
team. To address this, we propose a natural variant that we dub the Social
h-index. The idea is to redistribute the h-index score to reflect an
individual's impact on the research community. In addition to describing this
new measure, we provide examples, discuss its properties, and contrast with
other measures.
