Publishers have until 10th February 2017 to submit suggested humanities book titles to Knowledge Unlatched. Selected books are made Open Access in perpetuity, albeit usually minus the cover art/design as part of the Creative Commons PDF. Losses are defrayed by a consortium of libraries.
106 Knowledge Unlatched titles currently show up in OAPEN and thus in JURN. Although 343 titles were unlatched for 2016, which means that a lot more are coming soon.
