The German Research Foundation (DFG) has set the following conditions for the funding of publication fees:
1. The article must be published in a "genuine" open-access journal. The open-access journal in which the article is published must have quality-assurance procedures ("peer review") in place. All articles in those journals must be openly accessible free of charge immediately and completely as soon as they are published.
2. Publication fees may be paid from funds made available by the DFG only if they do not exceed €2,000 per article (19% VAT included).
3. Funding will be provided only if a Freie Universität member is responsible for the settlement of the publication fee as "submitting" or "corresponding" author.
5. No reimbursement will be made for publication fees that have been settled using external funding.
