Our Goals

DeepGreen is a delivery service for open access articles. We supply open access repositories with publisher content. Automated, legally compliant and targeted.

In doing so, we as DeepGreen strive for the following:

  • Technically reliable service for the allocation and delivery of publishers’ content.
  • The guarantee of common metadata standards and formats.
  • Targeted monitoring options and statistics.

Above all, we aim to increase the proportion of open access publications in repositories in Germany and beyond. We would like to invite all publishers and repositories to participate in DeepGreen: Join in!

Who we are

The library network Kooperativer Bibliotheksverbund Berlin-Brandenburg (KOBV), the Bayerische Staatsbibliothek and the University Library of the Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) are currently working together on DeepGreen – while maintaining their legal and economic independence. This is a project without its own legal entity. Please do not hesitate to contact us.

DeepGreen started as a multi-year DFG project funding with two phases. In the first project phase from 2016 to 2017, DeepGreen focused on licenses specifically funded by the DFG since 2011 and negotiated on a supraregional basis between publishers and libraries, the so-called alliance licenses, which contain special Open Access regulations. And, of course, to the fundamental technical development of the DeepGreen data hub.

From 2018 to 2021, the second project phase integrated further licensing models, such as open access transformation contracts, licences for subject information services (FID) or even golden open access models, and further developed the service for subject repositories in addition to serving institutional repositories. As of 2019, DeepGreen initially delivered data from seven publishers to 56 repositories on a nationwide level.

In the current pilot operation, DeepGreen is being further expanded and is working on the prospect of a sustainable funding model.
