ORCID

The ORCID ( ; Open Researcher and Contributor ID) is a nonproprietary persistent identifier, in the form of an alphanumeric code, to uniquely identify authors and contributors of scholarly communication. This addresses the problem that a particular author's contributions to the scientific literature or humanities publications can be hard to recognize, as most personal names are not unique, they can change (such as with marriage), have cultural differences in name order, contain inconsistent use of first-name abbreviations and employ different writing systems. It provides a persistent identity for humans, similar to tax ID numbers, that are created for content-related entities on digital networks by digital object identifiers (DOIs). The ORCID system includes a website and services to look up authors and their bibliographic output (and other user-supplied pieces of information).
