Research Analytics: Author IDs

Information on how to use research analytics tools to gauge research impact by author, article, or institution.

Author Identifiers

What are author identifiers and why do I need one?

Author identifiers, also called researcher identifiers, are unique numbers assigned to an individual. Their purpose is to distinguish between researchers, with the goal of associating the correct individual with all his or her published work. This is particularly important for researchers sharing the same name with other researchers or a researcher who has published under more than one name. A researcher working in two or more different fields of study will also benefit; others may wrongly assume the work has been done by different researchers who share the same name.

Several author identifiers exist, some of which you can request and others which are assigned to you. The chart below outlines the information on three different identifiers. You may have an identifier from each of these services which will be unique to that service. Some services will allow you to associate identifiers from other services with your profile.

The UW Libraries recommend establishing an ORCID (Open Researcher & Contributor ID).  The process is simple; follow the instructions at: During the registration process you have the option to associate your published works with your ID.

International Standard Name Identifier

One other author identifier you should know about is ISNI, the International Standard Name Identifier. This identifier can be assigned to researchers, inventors, writers, artists, visual creators, performers, and others. Individuals may not request ISNIs for themselves. Data can come from a variety of sources, including publishers. You can search the ISNI database to see if an identifier has been assigned to you and there is a mechanism for reporting corrections.
