With the support of Article Processing Charges (APCs), permanently unrestricted online access to published articles is allowed and our business can be kept sustainable. Only some fundamental costs like peer-review process, typesetting and copy-editing, archiving, online production in various formats, abstracting and indexing services, and inclusion in CrossRef are covered.
