EconStor is the new 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. Any research facility wishing to publish and permanently preserve relevant publications in economics under the terms of Open Access can do so on EconStor. EconStor offers a full service for entire working paper series and e-journals. This includes the uploading of PDF files as well as the processing of all corresponding title data such as abstracts, keywords and JEL codes. Scholars have the option of self-archiving their so-called postprints (free author’s versions of articles from publishers’ journals) to make them accessible. At “Publisher copyright policies & self-archiving (SHERPA/RoMEO database)” authors can find out whether a publisher permits parallel, free publication of previously published articles as postprints on EconStor.
