摘要
As unique and permanent alphanumeric strings to identify objects, digital object identifier (DOI) has been increasingly used to identify academic publications. Previous studies have reported the incorrect assignment of a single DOI name to multiple papers in the Scopus database, yet it remains unknown if this also holds in other datasets. In this paper we found incorrect DOI names are also problematic in the Web of Science but with different errors of duplicate DOI names. Tentative solutions are proposed in the end.
