Levitt JM, Thelwall M. Citation levels and collaboration within library and information science. Journal of the American Society for Information Science and Technology 2009;60(3):434-442.
This study, by examining the Web of Science (WoS) Information Science & Library Science subject category (IS&LS), found that collaboration varies with citation. In fact, collaboration is clearly associated with higher citation; whereas the collaborative rates and levels of the un-cited articles remained low and stable. With respect to the influential information scientists, they had high collaborative levels, but their more highly cited articles on average are not more highly collaborative than their less highly cited articles, even if, they tend to be published earlier.
Moreover, a new indicator of collaborative level is introduced: the average partner score, that can be used in other investigations of collaboration.
