crl-15781	Antelman, Kristin	Response to Philip Davis	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.
