To search the numer of citations per article or author, select Author field and type details of the author.
From results list select the Author, then click View citation overview
Scopus is a large abstract and citation database covering more than 15,000 peer-reviewed journals from over 4,000 international publishers. It contains scientific, technical, medical and social sciences literature, and has recently also included literature in the arts and humanities fields.
Scopus also offers tools to track, analyze and visualize research. One of them is the Journal Analyzer, which provides quick and easy view of journal performance. It also allows you to compare up to 10 journals. Full citation data are available from 1996 and are updated every two months.
After accessing Scopus, select Analytics.
You will then see Journal Analyzer page.
Search for a journal by title, ISSN or publisher. You can also limit your search by subject area.
From the result list, double-click on your desired journal to transfer it to the analyzer pane. Up to 10 journals can be added for comparison.
You can then evaluate journals using various journal parameters, including the two journal ranking metrics "SJR" & "SNIP".
To view a list of journal titles in Scopus, access the “Sources” page. Note that top journals cannot be identified within a specific subject field using Scopus. Refer to the “Finding journal publications in Scopus” box on this page for more.

The journal impact values in Scopus are calculated based on 3 years' citation data. Since full citation data are available from 1996 and the citation information for articles published prior to 1996 is not available, the first journal impact values are available in 1999.
SJR and SNIP are the two journal impact matrics used in Scopus. |

SJR (SCImago Journal Rank):
SJR is also called the "prestige" metrics, because in addition to the number of citations that a journal attracts, this metric also considers the prestige/quality of the citing journal.
Note that the prestige/quality of a citing journal is determined by the number of citations to this journal. Thus the calculation of SJR is an iterative process.
SJR also addresses different citation behavior in different subject fields by allowing journal's prestige to be shared equally between its citations. An arts and humanities journal with fewer citations, for example, has higher value for each of its citations. A science and engineering journal with more citations has lower value for each of its citations.
Each citation to a journal is weighted depending on the prestige of the source it comes from. A citation by a journal with a high prestige is valued highly, while a citation by a less influential journal is worth less.
SNIP (Source Normalized Impact per Paper):
SNIP measures the contextual citation impact by weighting citations based on the total number of citations in a subject field. It considers the citation potential (i.e. the likelihood of being cited) in a journal's subject field - including citing frequency, immediacy, database coverage.
A life sciences journal tends to have higher citation count, but at the same time higher citation potential. On the other hand, an arts & humanities journal is likely to have lower citation count and also lower citation potential. Because of this, the citation impact can be normalized, and direct comparison of journals across subject disciplines is therefore possible.
Other journal parameters:
Refer to the quick links on this page in the "Scopus search guides & tutorial" box on the right to access the search guides and tutorial and learn more about these metrics.
Scopus is a larger databaseand covers more Asian and humanities journals than Web of Science. If your desired journal does not have JCR Impact Factor, you can try to find whether it has SJR & SNIP in Scopus.
Journal Analyzer allows you to compare the SJR & SNIP of up to 10 journals using charts.
SJR takes into consideration other factors than just the number of cites – e.g. quality of citing journals; different citation behavior in different disciplines, self-citations (limits to the max. of 33%). It addresses the limitations and bias perceived with JCR Impact Factor.
Comparing the Impact Factors of journals across disciplines is extremely misleading because a top journal in the humanities field may have a much lower Impact Factor than a top journal in the science and engineering field. SNIP solves this problem because itallows direct comparison of journals across disciplines. The differences of journals’ SNIP are due to the quality of the journalsbut not the different citation behavior between subject fields.
