Citation rate, acceptance rate, listing in MEDLINE, circulation) are associated with higher methodological quality of a given publication. Likewise, Callaham et al. (2002) have found IF to be more important in the subsequent citing of a scientific paper than even the quality of the study methodology. Just as scientific literature is linked, so is information on the Web. Indeed, Ingwersen (1998) has proposed a Web impact factor measure that replaces citations in the IF formula with Web links and number of articles with number of pages on a site, with a correction for links to within the same site.
