Despite misuse and abuse, Journal Impact Factor
will retain its impact and won't fade away soon.
But I have first-hand experience, from when I was a researcher, of the Journal Impact Factor
being used inappropriately, and being judged on the journals I published in, rather than the discoveries I made.
His article 'Ultraviolet-light-driven enhanced hysteresis effect in graphene-tungsten disulfide heterostructures' was published in CARBON - one of the best journals in Engineering Sciences with an Impact Factor of 7.466 and ranked in the Q1 (topmost) category on both the Article Influence Score and Journal Impact Factor
In response to this scenario, a journal impact factor
(JIF) was created (Garfield, 1972).
While the over-reliance on any journal-level metric has its shortcomings, the impact factor, also known as journal impact factor
, remains one of the most widely used indicators of journal quality.
Many survey rankings and peer recommendations rely very heavily on the perception that a high citation metric--the Journal Impact Factor
(JIF)--is the best way to generate an initial list for ranking.
For example, a large literature documents the problems with journal impact factor
(JIF) for appraising citation impact.
NEJM has the highest Journal Impact Factor
of all general medical journals (2017 Journal Citation Reports, Clarivate Analytics, 2018).
The journal Impact Factor
is the average number of times articles from the journal published in the past two years have been cited in the Journal Citation Report (JCR) year.
Largely employed indicators embrace: Journal Impact Factor
or Eugene Garfield factor (JIF), Eigenfactor Score (ES), SCImago Journal Rank indicator, and H5 indicator (see Fig.
