Journal rankings typically use citation data to assess the quality of a given journal. The most well-known journal ranking system is the Journal Impact Factor (JIF), which is produced from citation counts collected from the Web of Science database. Other systems have been developed more recently, including Eigenfactor, Scimago Journal Ranking (SJR), Source Normalized Impact per Paper (SNIP), and SCOPUS CiteScore.
In this section, we focus on SCOPUS CiteScore and the Journal Impact Factor, however, we also have a brief explanation of other journal rankings.
The Journal Impact Factor
Please note that as of January 1, 2021 ASU Library has ended its subscription to Web of Science.
The Journal Impact Factor (JIF), using citation data from the Web of Science database (provided by Clarivate Analytics), is the original journal ranking product. JIF is a measure reflecting the annual average number of citations to recent articles published in a given journal. The full JIF information is found in the Journal Citation Reports (JCR) database which also includes Eigenfactor rankings and a five-year JIF. Selected JIF information can also be found directly in the Web of Science database. For a discussion of some of the issues associated with the JIF, please see the article below.
CiteScore is a product from Elsevier, using citation data from the Scopus database to rank journals. As with other journal ranking metrics, to compare journals across disciplines requires a "normalized" ranking, which CiteScore provides as a percentile ranking within the journal's subject category. In addition to the CiteScore number and percentile ranking, CiteScore also includes the SJR (Scimago Journal Rank) and SNIP (Source Normalized Impact per Paper) numbers.
The ASU Library acknowledges the twenty-two Native Nations that have inhabited this land for centuries. Arizona State University's four campuses are located in the Salt River Valley on ancestral territories of Indigenous peoples, including the Akimel O’odham (Pima) and Pee Posh (Maricopa) Indian Communities, whose care and keeping of these lands allows us to be here today. ASU Library acknowledges the sovereignty of these nations and seeks to foster an environment of success and possibility for Native American students and patrons. We are advocates for the incorporation of Indigenous knowledge systems and research methodologies within contemporary library practice. ASU Library welcomes members of the Akimel O’odham and Pee Posh, and all Native nations to the Library.
