The Impact Factors of a sample of journals have been                collected from Journal Citation Reports (JCR) provided by ISI. Changes in the Impact                Factors were monitored annually over two periods, 1994\u20131995 and                2000\u20132001, the years before and after electronic journals appeared. The                collected Impact Factors of scholarly journals from these two periods are compared                in the available media. As a result, it is found that Impact Factors of 2000 and                2001 were significantly higher than those of 1994 and 1995 in the journals published                by parallel publishing (combination journals\u2013simultaneous publication of                paper and electronic journals). In particular, the Impact Factors of the combination                journals increased after the journals transformed their available media from paper                journals to combination ones. By contrast, in the case of paper journals, there was                no significant difference betweenthe Impact Factors of 1994 and 1995 and those of                2000 and 2001. Additionally, it is possible to infer from later analyses that the                citation rate is not changed by the available media in the authoritative journals                which have comparatively high Impact Factors. In journals with low Impact Factors,                on the other hand, the available media influences the citation rate.<\/jats:p>","DOI":"10.1177\/0165551503296009","type":"journal-article","created":{"date-parts":[[2004,5,27]],"date-time":"2004-05-27T11:59:35Z","timestamp":1085659175000},"page":"527-533","source":"Crossref","is-referenced-by-count":18,"title":["Do Impact Factors change with a change of medium?
