This document discusses Nature Publishing Group's integration of ORCID identifiers. It outlines how authors can create or link an ORCID on nature.com and during manuscript submission. The corresponding author can search for co-authors using ORCID to pre-populate forms. NPG customer service can also find users based on ORCID. The document notes upcoming integrations like ORCID call-back APIs and completing the virtuous circle of data exchange between NPG, CrossRef, and ORCID.
