Journal Impact Factor

ICL JOURNALS>> JOURNAL IMPACT FACTOR

Eugene Garfield, founder of the Institute for Scientific Information, devised the impact factor in the 1950s. Impact factors are calculated each year by Thomson Scientific for the journals it indexes, and the factors are published in Journal Citation Reports (JCR).  View the JCR page for JMPT (November 19, 2010).

What is impact factor? According to Journal Citation Reports®: “[JCR]  offers a systematic, objective means to critically evaluate the world’s leading journals, with quantifiable, statistical information based on citation data. By compiling articles’ cited references, JCR Web helps to measure research influence and impact at the journal and category levels, and shows the relationship between citing and cited journals. Available in Science and Social Sciences editions.

Opinions vary as to the value of impact factors as measures of a journal’s value. Below is a selection of Open Access articles from peer reviewed journals, listed by date. Run a PubMed search: “Journal Impact Factor”[MAJR]  Free full text
