以前关于开放获取期刊对后续引用影响的调查混淆了开放和电子获取，并且未能跟踪随着时间的推移的可用性。通过新的数据，我们将这些影响分开。我们证明，一本期刊收到适度增加引用时，它是免费上网，但跳跃是更大的，当它第一次通过商业来源上网。这种效应在贫穷国家正好相反，因为在这些国家，免费获取的文章更有可能被引用。总之，研究结果表明，免费上网扩大了阅读和利用科学家调查结果的人的圈子。
Previous investigations into the impact of open-access journals on subsequent citations confounded open and electronic access and failed to track availability over time. With new data, we separated these effects. We demonstrate that a journal receives a modest increase in citations when it comes online freely, but the jump is larger when it first comes online through commercial sources. This effect reverses for poor countries where free-access articles are much more likely to be cited. Together, findings suggest that free Internet access widens the circle of those who read and make use of scientists' investigations.
