ORCID & Author IDs: Unique Author IDs

Name Authority

When publishing an article, consider how unique your name is at your institution or nationally at the research level.   Databases such as Web of Science and Scopus attempt to connect your publications together for impact and h-index calculations.   However, the more common your name is, the more difficult it can be to distinguish you from other authors.   When publishing an article, consider using not only your first name, but your second name or first initial of your second name to help disambiguate your name from other researchers.   

Some databases such as Web of Science and Scopus assign unique author IDs to help connect articles from one author.   However, these author IDs are unique to the specific database, and they may not completely unit all your publications together under one ID if you belong to multiple departments or have worked at multiple institutions.
