The Rise and Fall of Uncitedness	1997-01-01	11	.pdf	application/pdf	6435	251	50	For example, in sociology, �73 percent of the variance in article citations was within journals; thus, there is roughly three times as much variation within journals as between them.�18 Therefore, estimating the long- term significance of an article by the per- ceived quality or impact factor of the journal in which it appears is simplistic: Assigning the same value to all ar- ticles in a journal will overestimate the less influential and underesti- mate the more influential articles, thus effectively leveling out the very differences that [citation] evaluation procedures should seek to identify.19 In general, basing a citation study on a small set of prestigious journals will re- duce uncitedness substantially. Is that similar to the vari- ance within other LIS journals?	cache/crl-15100.pdf	txt/crl-15100.txt
