“…As Zhao & Logan (2002) point out, some studies apply, often with modifications, informetric principles and techniques to study the characteristics and link structures of the Web. Examples include studies on search engines that make use of hyperlink structure (Clever, 1999), and so-called "Webometrics" studies (Almind & Ingwersen, 1997;Cronin et al, 1998, Egghe, 2000Larson, 1996;Rousseau, 1997;Thelwall & Harries, 2004;Turnbull, 2000;Wilkinson et al, 2003). Other studies consider "electronic ingredients" in journal articles -either in reference lists or in abstracts -to gauge the impact of electronic publications on traditional print journal-based scholarly communication (Harter, 1992;Harter & Kim, 1996;ISI, 2004a;Lu, 1999;McCain, 2000;Youngen, 1997).…”
