Authors also need to be identified unambiguously. There is often more than one author with the same name, and the same author's name isn't always stated the same way. This is a huge problem for academic authors: their income and status are dependent not just on writing articles and books, but for those works being cited. This has led to the development of ORCID, the Open Researcher and Contributor ID, which provides disambiguation of author names for scholars and researchers.
