Specifying your author-role on scholarly outputs provides a nuanced view on your contribution(s) to a research output, revealing your specialties (skills and expertise).

Although not completely without issues[1], a tool to describe your author role is the structured Contributor Role Taxonomy (CRediT), introduced in 2014, used by many journals and accepted by the National Information Standards Organization (NISO) as a NISO-norm.

When acting as the corresponding author mention this as well as this role is an indicator of leadership, especially for co-authored publications by international teams. [2]
