Some other unique author identifiers were developed before ORCID was available. Scopus' AuthorID is one. Unlike ORCID, Scopus' AuthorID is connected to a proprietary, subscription based system, namely Elsevier's Scopus database. Scopus AuthorIDs are assigned by an algorithm when articles are indexed for inclusion in the Scopus database.
Advantages of Scopus Author IDs
- It's automatically created Enables you to easily get your citation metrics like the h-index
- Can be connected to ORCID and MCW's Faculty Collaboration Database to automatically pull in publications to your profile
Limitations of Scopus Author IDs
- Since author disambiguation is difficult, you may be assigned more than one ID. There are relatively easy ways to correct this.
- This is only available to collect together publications indexed in Scopus. If you have publications in sources not indexed by Scopus, you cannot add them.
