Open Access


Open Access is the practice of providing online access to scientific information (articles, monographs, research data and other research outputs) that is free of charge to the reader, and licensed so that they can be further used and exploited by researchers, the industry and citizens.

Milestone definitions of Open Access include those of the Budapest Open Access Initiative (BOAI) and the Berlin Declaration (October 2003) on Open Access.
