This page is designed to provide researchers with information on the number of times a publication has been cited.
Searching for cited articles can be useful for conducting research for the following reasons:
- Discover other works related to your research topic
- Identify researchers with similar research interests
- Assess the relevance of a particular work by checking how frequently it has been cited by other researchers or publications
Scopus is undergoing migration to a new back-end system to be completed by the end of 2025. In some cases, users may encounter differences between the citation count shown on the Citation overview page and other pages in Scopus due to the different synchronization cycles of the new and old backend systems. Be assured that citation count data on all Scopus pages remains accurate. Read more

Considerations
The number of citations depends on the content and coverage of the source.
WOS
- Citation data is available only for records indexed by the database
- A limited number of journals are included
- European bias.
- Calculates the h-index of an author from 1965 – current
- A limited number of journals in non-English languages
- Clear results from scholarly journals.
- Articles “in press” are not indexed due to editorial policy, and only the final version is included
- The option to exclude self-citations
- Access via subscription
SCOPUS
- Citation data is available only for records indexed by the database
- More content (about 22,000 journals) than in WOS (about 12,000 journals)
- American bias
- Calculates the h-index of an author from 1996 – current
- Scopus Cited References Expansion Program ensures cited references going back to 1970 will be added to pre-1996 Scopus content in the fourth quarter of 2014
- A limited number of journals in non-English languages
- Clear results from scholarly journals
- One version of a paper in results
- Articles “in Press” are indexed
- Self-citations exclusion option
- Access via subscription
GOOGLE SCHOLAR
- Scholar’s work may be published in journals not covered by WOS and Scopus.
- Larger number of journals than in WOS and Scopus *not all scholarly journals are indexed in Google Scholar.
- Larger number of publications in non-English languages than in WOS and Scopus.
- Value of H-index may vary because of additional irrelevant citations results from non-scholarly citations (records from unknown sources and informal material).
- Not all of journals are of the same quality as those found in the Web of Science or Scopus.
- In some cases Scholar indexes preprint and journal version of a paper and provides in the results the sum of the two counts, so citations are spread over the duplicates.
- Provides an H-index only for researchers who created a user profile for themselves.
- Counts self-citations.
- Freely accessibly from the internet.
CITESEERX
- CiteSeerX focuses primarily on the literature in computer and information science.
- Uses ACI (Autonomous citation indexing) to automatically extract citations and create a citation index.
- Computes citation statistics and related documents for all articles cited in the database, not just the indexed articles.
The optimal methodology to count citations is to consult Google Scholar and other sources in addition to Web of Science or Scopus.
- Disciplines that cite more references per paper are expected to drive up the Impact Factor of the journal
- The same journal may be ranked differently depending on the category being reviewed
- Different disciplines have different standards for citation:
- Journals indexed in the WOS cover mainly the core disciplines in the natural sciences.
Journals indexed in the WOS and Scopus do not sufficiently cover fields such as computer science. - Journals indexed in the Web of Science do not sufficiently cover the field of engineering science either.
- Google Scholar’s coverage in disciplines such as Biology, Chemistry, and Physics is lower compared to Web of Science (WOS) or Scopus. However, Google Scholar provides broader coverage for the four social science disciplines—Education, Economics, Sociology, and Psychology—as well as Computing, compared to WOS and Scopus.
- The number of Google Scholar citations for mathematicians and computer scientists is higher than that in Web of Science (WOS) and Scopus, but lower for high-energy physicists.
- Journals indexed in the WOS cover mainly the core disciplines in the natural sciences.
- Coverage in different disciplines is not the same in different sources
- Large and small journals are compared equally.
- Smaller or more specialized journals will tend to have smaller Impact Factors.
Instructions
Web of Science database provides various options for finding citations related to specific articles or research.
- Basic Search
- Select the ‘Title’ search option in the Basic Search box, enter the title of the work, and click ‘Search’.
The results screen will display the number of citations for a given work. - To see the list of articles that have cited a given work, click on the number of ‘Times Cited’
Note: In this method, citing articles are available only from subscribed databases
- Select the ‘Title’ search option in the Basic Search box, enter the title of the work, and click ‘Search’.
To see more information about ‘Times Cited Counts’, click ‘View Additional Times Cited Counts’.
- Cited Reference Search
- To find out how many others have cited a given work, choose one or more of the search options in the search box in Cited Reference Search (author, title, journal, etc.)
- Then click ‘Search’.
The results screen will display the number of citations for a given work.
To find out which articles have cited a work, select the reference and click ‘Finish Search’.
Note: It is recommended to perform a Cited Reference Search* to include citations to items not indexed in the product
On a document’s metrics details page in Scopus, you can find four specific metrics:
- The total citations within a specified date range
- The average number of citations per year over a selected period, citation benchmarking (percentile)
- The Field-weighted Citation Impact (FWCI)
Additionally, a “Views count” is provided to give you a quick overview of the document’s usage.
