WoS as a source of citation information

WoS, along with Scopus-database, is an important database containing citation information especially for medicine and natural sciences.  WoS contains citation information since beginning of the 1900´s. Moreover WoS is the database with fewest mistakes compared to other databases.

Journal Impact Factor -indicator is counted based on WoS citations. Impact Factors can be search in Journal Citation Reports -database.

Cited reference search
is recommended for searching comprehensively all the citations an article or author has received. Citation information (count of citations)  is not dependent on the WoS-lisence of Oulu University Library. Complete bibliographic information instead is available for only those citations that belong to WoS Core Collection.

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. University of Oulu currently subscribes to citation indexes and years of coverage as follows: Science Citation Index Expanded (1975 - present), Social Sciences Citation Index (1975 - present), Arts & Humanities Citation Index (1975 - present). Web of Science always includes all the cited references for every record created, irrespective of the publication year.

Scopus includes cited reference information for records of papers published from 1970 onward. There can gap in the coverage of journals in Scopus.

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.

Web of Science and ResearcherID


After registration in the ResearcherID service researchers can create a researcher profile and through it maintain their list of publications. They can also supplement their profiles with affiliation information and monitor both the citation data and h-index from the Web of Science.


Up-to-date citation data is received from the Web of Science.

ResearcherID is integrated with Web of Science, making it is easy to add publications to your own researcher account. You can also import articles in the RIS format from other databases and reference software. Your ORCID account can be associated with your ResearcherID and data can be exchanged between these two.
