The Affiliation Details page provides information about affiliations that have more than one document matched to them in Scopus. Affiliation details include the affiliation ID, name variations, address information, research areas, documents published, sources the organization has published in, and collaborating affiliations.

Researcher profile in Scopus

Scopus automatically creates researcher profiles with author identifiers. Researchers can request for corrections, if needed. For example if:

  • your publications are listed under several author identifiers, you can ask Scopus to merge the identifiers ("Request to merge authors")
  • there is false or missing information in your profile, you can ask Scopus to correct or complete your researcher profile information ("Request author detail corrections")
  • there are publications that are not written by you listed under your researcher profile, you can ask Scopus to remove them ("Request to remove documents from author")

Requests can be made directly in Scopus or through a separate Author Feedback Wizard .

Comparison of Web of Science, Scopus and Google Scholar

The most important multidisciplinary databases containing citation information are Web of Sciece (WoS) by Thomson Reuters and Scopus by Elsevier.  Citations can also be retrieved from Google Scholar (GS) keeping in mind the limitations of the database. GS contains a lot of non-scientific citations. The number of citations can vary a lot between Web of Science, Scopus and especially GS.

In addition, there are some field specific databases which contain reference information such as Chemical Abstracts (SciFinder), CiteSeerX and MathScinet.

Google Scholar Profile

From the perspective of citation analysis, what matters most, is the number of records enhanced by cited references and the total number of cited references included in the database used. In addition to contributing citation data, citation enhanced databases may serve as a platform providing the analytical tools for bibliometric analysis. Both of these contributions are beset with several methodological and technical difficulties, including limited coverage of the scholarly literature, inconsistent and inaccurate data, and limited facilities for browsing, searching and analyzing data. Most of these difficulties arise because bibliographic databases are primarily designed for information retrieval and bibliometric analysis represents only a secondary use of the systems.

Both Web of Science and Scopus have master records with cited references, and they show the bibliographic and reference details of the citing records. Web of Science is available in many different versions regarding years of coverage and citation indexes included in the subscription of the user's institution. Web of Science always includes all the cited references for every record created, irrespective of the publication year and subscription. Scopus includes cited reference information for records of papers published from 1970 onward.

Google Scholar's coverage is unknown and might be uneven across different fields of science. Additonally, older publications are poorly covered. To continue non-scholarly literature and citations are included.
