ORCID (Open Researcher and Contributor ID) is a type of author identifier.
ORCID aims to solve the name ambiguity problem in research and scholarly communication by creating a central registry of unique identifiers for individual researchers and an open and transparent linking mechanism between ORCiD and other current researcher ID schemes. These identifiers, and the relationships among them, can be linked to the researcher’s output to enhance the scientific discovery process and to improve the efficiency of research funding and collaboration within the research community. ORCID is a non-profit organization funded by institutional memberships, grant-making organizations, and a wide variety of research organizations and publishers.
An ORCID identifier, or ORCID id, is a persistent, unique, numeric identifier for individual researchers and creators. It distinguishes you from other researchers with the same (or very similar) name and supports automated linkages between you and your research activities. Your ORCID record, which includes your ORCID identifier, holds non-sensitive information such as name, organization, and research activities.
Since many major publishers and other information producers are integrating ORCID identifiers into their products and tools, having an ORCID identifier may help simplify processes like journal article manuscript submission.
ORCID has a simple registration form for obtaining an identifier. You are asked to include your name and email, create a password for your ORDIC account, accept terms and conditions, and decide on visibility settings for your ORCID record. The ORCID record is a personal profile that is associated with an ORDIC ID. Users can add information about their education, employment, funding, and publications and can include all variations of their name, a personal website, and keywords associated with their work.
While users can manually add publications to the ORCID profiles, ORCID also facilitates the easy import of references from several databases and systems. A complete list of supported systems is available on the ORCID website, along with a help video on how to search and link references:
Users can also add references to their ORCID records through a BibTeX (.bib) file. A BibTeX file is a plain text file containing bibliographic information. As ORCID explains, "BibTeX files can be created and edited using many popular reference management tools, such as Google Scholar Citations, EndNote, Papers, etc." For information about how to import references using a BibTeX file, please see ORCID's guidance.
