The DOI and why it matters in scientific publications

Abstract

Digital Object Identifier (DOI)
The DOI, or Digital Object Identifier, is a unique alphanumeric string that is assigned to digital objects, such as research papers, to provide a persistent and unique link to the paper. It is like a social security number for the cited article. Web addresses might change, but DOI will stay the same permanently. The DOI system was created by The International DOI Foundation (IDF) a non-profit organization introduced in 1997 and adopted as International Standard ISO 26324 Registration Authority in 2012. The final original standard was published on 23 April 2012, and was updated in 2022.
