Chaudhuri J, Thohira M. Usage of open-access journals: findings from eleven top science and medical journals. The Serials Librarians 2010;58(1):97-105
Usage patterns of open-access and hybrid-open-access journals in selected scholarly publications are outlined. More than 1,100 citations from eleven top science and medical journals for the years 2004, 2006 and 2008 were analyzed. 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.
