Scientists from Finland and Germany have taken on the task of researching the history of Open Access journal publishing over the last 17 years. Their article “The Development of Open Access Journal Publishing from 1993 to 2009” was recently published in PloS One. Looking at the history of Open Access (OA) and evaluating the publishing trends they were able to determine that the greatest growth is from 2000-2009 in the number of OA journals established and thus in the number of OA articles produced. Although the percent overall of articles published each year that are OA is still small, the trend doesn’t look to be slowing down. They estimate that by the end of 2011 one third of all scientific articles will be open access.
