Title: Journal Impact Factor, Eigenfactor, Journal Influence and Article Influence
Abstract: This paper examines the practical usefulness of two new journal performance metrics, namely the Eigenfactor 
	score, which may be interpreted as measuring “Journal Influence”, and the Article Influence score, using the 
	Thomson Reuters ISI Web of Science (hereafter ISI) data for 2009 for the 200 most highly cited journals in 
	each of the Sciences and Social Sciences, and compares them with two existing ISI metrics, namely Total 
	Citations and the 5-year Impact Factor (5YIF) of a journal (including journal self citations). It is shown 
	that the Sciences and Social Sciences are different in terms of the strength of the relationship of journal 
	performance metrics, although the actual relationships are very similar. Moreover, the journal influence and 
	article influence journal performance metrics are shown to be closely related empirically to the two existing 
	ISI metrics, and hence add little in practical usefulness to what is already known. These empirical results 
	are compared with existing results in the literature.
