“…With regard to generic criticism, the following must be underlined: language bias, with an overwhelming predominance of journals in English [MUELLER & AL., 2006], seminal articles and review articles receiving excessive citations [AKSNES, 2006;GARFIELD, 1996], the very process of gathering and processing so much information may cause errors [BUCHANAN, 2006;GARFIELD, 1996;JACSÓ, 2006;MOED & VRIENS, 1989] and the inappropriate definition of citable documents [GARFIELD, 1998;GLÄNZEL & MOED, 2002;MOED & VAN LEEUWEN, 1995;MOED & AL., 1999]. Other criticisms are specifically aimed at the calculation method employed by ISI for impact-factor construction [ADAM, 2002;GLÄNZEL & MOED, 2002;MOED, 2002;SEGLEN, 1997A,B;WHITEHOUSE, 2002].…”
