Usage of Open-Access Journals: Findings from Eleven Top Science and Medical Journals

Abstract

In this article, usage patterns of open-access and hybrid-open-access journals in selected scholarly publications are outlined. The authors analyzed more than 1,100 citations from eleven top science and medical journals for 2004, 2006, and 2008. The eleven high- impact journals included eight traditional, one open-access, and two hybrid-open-access journals. In most cases, the data show that the usage of open-access journals increased from 2004 to 2008. © The North American Serials Interest Group, Inc.
