Does international collaboration yield a higher citation potential for US scientists publishing in highly visible interdisciplinary Journals?

Generally, multicountry papers receive more citations than single-country ones. In this contribution, we examine if this rule also applies to American scientists publishing in highly visible interdisciplinary journals. Concretely, we compare the citations received by American scientists in N ature, S cience, and the P roceedings of the N ational A cademy of S ciences of the U nited S tates of A merica ( PNAS). It is shown that, statistically, American scientists publishing in N ature and S cience do not benefit from international collaboration. This statement also holds for communicated submissions, but not for direct and for contributed submissions, to PNAS. [ABSTRACT FROM AUTHOR]
