Harvesten der SSOAR-Metadaten über OAI-PMH-Schnittstelle möglich

1. Are documents stored in SSOAR citable?

Many people still think that electronic repositories are less secure than other sources and that lasting access to their content is not possible. Contrary to this persistently-held view, documents stored in SSOAR are citable on a long-term basis. A Uniform Resource Name (URN) is generated for each document archived in SSOAR. This URN ensures the citability of the document.

With regard to the formal guidelines for citing online sources, there are different standards, depending on the discipline in question and the publisher/journal in which the SSOAR document is to be cited. As a matter of principle, you should always cite the relevant bibliographic data of the work in question and the URN.
