The proportion of freely accessible journal articles published by researchers in Berlin increased again. As the Open Access Bureau Berlin and a team from various universities has determined, during the survey period of 2018, about 41.5 percent of the articles published by researchers at the universities, including the universities of applied sciences, in the state of Berlin were available through open access. The proportion of such articles thus increased by 3 percentage points as compared with 2017 (38.5 percent). Roughly 19.4 percent were publications that were published in open access journals (gold open access), 15.0 percent were published in open access in addition to other journals (green open access), and 7.1 percent were published as an open access version in closed access journals (hybrid open access). The latter are subscription-based journals that make individual articles available for a fee. According to the authors of this survey, Berlin is well on its way to reaching its self-imposed target of publishing 60 percent of its academic publications in open access journals by 2020. This goal was set in the Open Access Strategy for Berlin adopted by the Berlin House of Representatives in 2015. This strategy aims to ensure that findings from research conducted at public universities funded with taxpayers’ money are available without financial, legal, or technical barriers not only for the scientific community, but also for the broader public, businesses, and associations.
