IFIRST MENTIONED THE IDEA OF AN IMPACT FACTOR IN Science in 1955. With support from the National Institutes of Health, the experimental Genetics Citation Index was published, and that led to the 1961 publication of the Science Citation Index. Irving H. Sher and I created the journal impact factor to help select additional source journals. To do this we simply re-sorted the author citation index into the journal citation index. From this simple exercise, we learned that initially a core group of… Expand

Topics from this paper

Journal impact factor in the era of expanding literature.
TLDR
The effects of the rapidly expanding literature on the impact factor over the past decade is examined and the limitations of journal impact factor for evaluating individual author's contributions are examined. Expand
The delicate topic of the impact factor
TLDR
Although even Thomson Scientific acknowledges that the impact factor has grown beyond its control and is being used in many inappropriate ways, the impact factors of journals have been used to decide whether or not authors get promoted, are given tenure or are offered a position in a department, or are awarded a grant. Expand
The Evolving Significance and Future Relevance of the Impact Factor
TLDR
The impetus to publish in high-IF scientific journals has reached a point where it has become detrimental to science, and editors for the American Society for Microbiology journals have recently decided to remove IF content from their journals’ websites so as to bring the focus back on publishing high-quality science. Expand
Journal Impact Factors: Their relevance and their influence on society-published scientific journals
We examine the nature and temporal trends of science journal publishing, and seek to explain why some journals have higher Journal Impact Factors (JIF) than others. The investigation has implicationsExpand
100 papers to read before you die.
  • J. Evers
  • Medicine, Biology
  • Human reproduction
  • 2010
TLDR
Peer review helps journals to provide the type and quality of material they are aiming to publish for their specific audiences, and publishing highly cited articles will increase a journal’s impact factor, and therefore standing. Expand
Impact factor: Universalism and reliability of assessment.
TLDR
The impact factor (IF) concerns a research discipline called bibliometrics, which uses mathematical and statistical methods to analyze scientific publications and has become a fundamental and universal measure of the journal's value. Expand
Impact versus Significance in scientific publishing
  • Medicine
  • European journal of immunology
  • 2015
TLDR
This year’s impact factor is the number of citations in 2014 for articles published in 2012 and 2013 in a given journal, divided by theNumber of all source articles (typically research and review articles) published in 2013 in that given journal. Expand
Comparison of SCImago journal rank indicator with journal impact factor
TLDR
Although further validation is warranted, the novel SJR indicator poses as a serious alternative to the well‐established journal IF, mainly due to its openaccess nature, larger source database, and assessment of the quality of citations. Expand
Article-count impact factor of materials science journals in SCI database
TLDR
It was found that ACIF index could be used as an alternative tool in assessing the journal quality, particularly in the case where the assessed journals had the same (equal or similar) JIF values. Expand
Hard Impact: Journal Impact Factor and JMT
TLDR
In the fall of 2008, the University of Pennsylvania Press submitted to the Institute of Scientific Information (ISI) a request that JMT be evaluated for inclusion into the Web of ScienceSM, and in January of this year, JMT received word that its request for inclusion was rejected. Expand

Which medical journals have the greatest impact?
TLDR
High-impact medical journals are identified using data from the 1981 and 1982 Journal Citation Reports, an annual supplement to the Science Citation Index that ranks journals by the number of citations received. Expand
How well does journal 'impact' work in the assessment of papers on clinical physiology and nuclear medicine?
TLDR
Although a phase of no citation was identified, which gave a lower citation factor than the journal impact factors, the citation frequency increased over time, and altogether there seems to be a good agreement between journal impact factor and overall citation frequency of papers on clinical physiology and nuclear medicine. Expand
Algorithmic procedure for finding semantically related journals
TLDR
A new procedure using citations, papers and references as parameters a relatedness factor (RF) is computed for a series of journals and appears to select a set of journals that are semantically most similar to the target journal. Expand
Bibliographic and Web citations: What is the difference?
TLDR
This work compared bibliographic and Web citations to articles in 46 journals in library and information science to find that Web citations correlated significantly with both bibliographs listed in the Social Sciences Citation Index and the ISI's Journal Impact Factor. Expand
Rank-normalized impact factor: A way to compare journal performance across subject categories
TLDR
A rank normalized impact factor (rnlF) is proposed which involves use of order statistics for the complete set of journals within each JCR category and it is believed the normalization procedure provides reliable and easily interpretable values. Expand
Is the ratio between number of citations and publications cited a true constant
The first experimental citation indexes of scientific literature were compiled almost twenty years ago. By the time we had completed the 1964 Sczknce Citu-tion Inde# (SCF'), we were aware that thereExpand
Citation analysis as a tool in journal evaluation.
TLDR
In 1971, the Institute for Scientfic Information decided to undertake a systematic analysis of journal citation patterns across the whole of science and technology. Expand

  • Psychology, Medicine
  • Bulletin of the Medical Library Association

TLDR
Although the Gross and Gross method has been in use for almost twenty years, the fundamental assumptions upon which the method is based have never been examined and an investigation has been undertaken to examine these assumptions. Expand
Long-term vs. short-term journal impact: does it matter?
TLDR
The first published report on journal impact factors was included in E. Garfield, I.H. Sher, and the late Irving H. Sher's American Documentation, 14[3]:195-201, July 1963. Expand
Free online availability substantially increases a paper's impact
TLDR
The results are dramatic, showing a clear correlation between the number of times an article is cited and the probability that the article is online, in computer science. Expand
