A scholarly identifier is a tool to help organize and link your full body of academic work. Researchers can easily establish a digital identifier in both ORCID , Google Scholar, or Research Identifier and then begin attributing their work to these accounts. This process creates a digital body of work to pool your citations, publications and research interests.
What is ORCID?
ORCID is an open, non-profit, community-based effort to provide a registry of unique researcher identifiers and a transparent method of linking research activities and outputs to these identifiers. This is a convenient way to quantify, organize and share the full scope of your academic identity within a single identifier.
Researcher ID is a Thomson Reuters Product and can be of especial importance to users who utilize the Web of Science. You can learn more about ResearcherID via ths link. This tool can also be associated with your ORCID account.
"Google Scholar Citations provide a simple way for authors to keep track of citations to their articles. You can check who is citing your publications, graph citations over time, and compute several citation metrics. You can also make your profile public, so that it may appear in Google Scholar results when people search for your name, e.g., richard feynman.
Best of all, it's quick to set up and simple to maintain - even if you have written hundreds of articles, and even if your name is shared by several different scholars. You can add groups of related articles, not just one article at a time; and your citation metrics are computed and updated automatically as Google Scholar finds new citations to your work on the web. You can choose to have your list of articles updated automatically or review the updates yourself, or to manually update your articles at any time."
