crl-15780	Davis, Philip M.	Letter to the Editor	2006-03-01	3	.pdf	application/pdf	1405	61	50	In 2001, Kent Anderson and others published a citation study of the journal Pediatrics.6 Using three years of data, they compared articles printed in the journal and available online by subscription with other articles appearing only in a free online addition. Article Duplication as Cause From 1975 through 2003, Emerald (for- mally MCB University Press) engaged in substantial article duplication, where hundreds of articles were republished in different journals with no indication of their original source.3, 4 This dataset provides a natural controlled experiment to test whether the simple act of article duplication may explain increased cita- tion impact.	cache/crl-15780.pdf	txt/crl-15780.txt
