The feasibility and sustainability of Open Access (OA) journals and articles has been debated for over a decade [1-3]. Even with the ongoing debate, open access to scientific journal articles continues to gain momentum. Since 1993, open access journal articles have grown to account for 7.7% of all peer-reviewed published journal articles in 2009 [4] and 12% of all journal articles in 2012 [5]. Laakso and Bjork [6] comment, “It no longer seems to be a question whether OA is a viable alternative to the traditional subscription model for scholarly journal publishing; the question is rather when open access publishing will become the mainstream model.”
