The CBS LibGuide about Journal Metrics and Rankings takes you through the most commonly used journal citation indicators.
These indicators use citations as a proxy for quality and impact of a journal, and based on these ranking lists of the best journals are produced.
Note that when trying to establish the quality or impact of a specific journal, it is recommended that you supplement the citation based indicator data with data about how the journal performs in other journal rankings (see box titled "Non-citation based ranking lists").
Journal Impact Factor (JIF) is perhaps the best known and most used metric for quality ranking of scientific journals measured by how many times articles are cited.
Data: The JIF is based on Web of Science citation data. JIF's are located in Journal Citation Report, sourced from the Web of Science Core Collection
This is how you find a JIF:
How JIF is calculated
The JIF is calculated as the average number of times articles from the journal published in the past two years have been cited in the JCR year. Example - Organization Science
Not 'field normalized'
It is important to know that the JIF is not field normalized which means that it doesn't take account for the different citation patterns from discipline to discipline. Therefore you should only compare JIFs for journals in the same discipline.
Relevant CBS subject categories
Note that only a limited number of CBS-relevant journals are indexed in Web of Science, and thereby have a JIF. The most relevant subject categories for CBS are Economics with 353 journals, Management with 210 journals, Business with 140 journals, Business/Finance with 98 journals, and Operations Research and Management Science with 84 journals - a total of 885 CBS relevant journals.

CiteScore is the equivalent to JIF. It is also a metric for quality ranking of scientific journals measured by how many times articles are cited.
Data: CiteScore is based on data from the citation database Scopus.
This is how you fnd a specific journals CiteScore:
How CiteScore is calculated
CiteScore is calculated as the average number of times articles from the journal published in the past three years have been cited in a specific year. So CiteScore uses a 3-year citation window, as opposed to JIF's 2-year citation window. Example - Organization Science
Not 'field normalized'
Like JIF CiteScore is not field normalized – so you should only compare journals within the same field/subject category.
Number of CBS relevant journals with a CiteScore
There are more CBS-relevant journals with a CiteScore than a JIF. The most relevant CBS subject areas in Scopus are Business, Management and Accounting with 1719 journals, Computer Science with 2141 journals, Economics, Econometrics and Finance with 1152 journals and Social Sciences (Sociology and Political Science, Cultural Studies and Communication) with 2277 journals - a total of 7289 CBS relevant journals.

When trying to establish the quality or impact of a specific journal, it is recommended that you supplement the citation based indicator data with data from other journal rankings.
Here are some examples of ranking lists of journals from CBS relevant research areas:
JIF is based on data from Web of Science, wheras CiteScore is based on data from Scopus.
CiteScore uses a 3-year citation window whereas JIF uses a 2-year citation window.
Several other journal metrics are available. These metrics address the following issues:
Note that JIF and Citescore produces more or less the same ranking of journals within a subject field, as they are calculated in very similar ways. But rankings based on more advanced metrics can be much more different!
