Does free access to journal articles result in greater diffusion of scientific knowledge? Using a randomized controlled trial of open access publishing, involving 36 participating journals in the sciences, social sciences, and humanities, we report on the effects of free access on article downloads and citations. Articles placed in the open access condition (n=712) received significantly more downloads and reached a broader audience within the first year, yet were cited no more frequently, nor… 
The influence of funding on the Open Access citation advantage

The impact of free access to the scientific literature: a review of recent research.
TLDR
Recent studies provide little evidence to support the idea that there is a crisis in access to the scholarly literature, and further research is needed to investigate whether free access is making a difference in non-research contexts.
The Effect of Open Access on Research Quality
The number of articles being published open access has been increasing and some research funders are starting to mandate their researchers to publish solely in open access-only journals. Reasons to

The citation advantage of open-access articles
