Xia J, Myers RL, Wilhoite SK. Multiple open access availability and citation impact. Journal of Information Science 2011;37:19-28
The study examines whether there is a direct correlation between multiple open access (OA) availability of journal articles and the citation advantage by collecting data of OA article appearance and citations in 20 top library and information science (LIS) journals published in 2006 (total number 875). Multiple OA availability refers to multi-locations and multi-versions of an OA article. The analysis demonstrates a statistical significance for a correlation between OA status of LIS articles and a positive impact on their citation account.
