The IHS Library provides the IHS departmental series in three subject-based repositories:


RePEc (Research Papers in Economics) is a collaborative effort of hundreds of volunteers to enhance the dissemination of research in Economics and related sciences. It is is a decentralized database of working papers, journal articles and software components. All RePEc material is freely available.

EconStor is the Open Access server of the German National Library of Economics – Leibniz Information Centre for Economics. EconStor provides a basis for the free publication of academic literature in economics. Scholars have the option of self-archiving their so-called postprints (free author’s versions of articles from publishers’ journals) to make them accessible.

EconStor currently provides access to working papers from approx. 100 institutions. Among these are the six top-rated German economic research institutes and the Deutsche Bundesbank.


The Social Science Open Access Repository (SSOAR) is an open-access document server for the social sciences which indexes and archives scholarly literature (full texts) from the social sciences in Germany and abroad.

SSOAR offers scholars and scientists from the social sciences and neighbouring disciplines an organisational and technical framework in which they can make their documents electronically available. However, SSOAR is not a publishing venue. Rather, it serves to make published documents available on the Internet for research and education purposes.
