JSTOR (ITHAKA) is a non-profit organization dedicated to preserving and increasing access to scholarly journal literature. JSTOR has created a high-quality, interdisciplinary “trusted digital archive for scholarship”. The JSTOR archives include scholarship published in the highest-quality academic journals (incl. the HSR-Journal and the HSR-Supplement, moving wall: two years) across the humanities, social sciences, and sciences, as well as monographs and other materials valuable for academic work. JSTOR has created an electronic archive of the complete back runs of over 1,000 journals in 50 disciplines. More than 6,000 academic institutions and over 700 scholarly publishing organizations around the world participate in this endeavor (since 1995).
SSOAR (Social Science Open Access Repository / GESIS) 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. SSOAR includes HSR-articles from back issues (moving wall: two years). SSOAR is an open-access full-text server, SSOAR’s goal is to implement the “green road” to open access by providing users with free electronic access to journal article preprints and postprints and also to other document types. SSOAR saves, catalogues and archives scholarly and scientific electronic documents from the social sciences. These documents can be either born-digital publications or digitised versions of print works (since 2007).
