What is a unique author ID?

Martin Fenner's 2011 article in Libreas, Author Identifier Overview ( and provides an excellent introduction to why unique author identifiers are necessary:

"We have long assigned unique numbers to genes, species or stars, and have used unique identifiers for scholarly works for more than 10 years, but unique identifiers for authors are still fairly new and not yet in widespread use(1). Unique author identifiers are useful for the following reasons (2-8):

  1. Researchers want to find potential collaborators, and want an easier way to get credit for their scholarly activities,
  2. Institutions want to collect, showcase and often evaluate the scholarly activities of their faculty,
  3. Publishers want to simplify the publishing workflow, including peer review,
  4. Funding organizations want to simplify the grant submission workflow and want to track what happened to the research they funded, and
  5. Scholarly societies want an easier way to track the achievements of their members."
