ELPUB can look back on a track record of a steadily growing number of conference papers. From a longterm perspective, access to this body of knowledge is of great interest to the community. Beyond this, extended preoccupation with the collected scientific work in the area of digital publishing has to be mentioned. Naturally, the authors are particularly focussed on the individual paper itself and possible connections with related efforts. Typically, conferences amplify and enhance opportunities of “gettingtogether”. A well-stocked repository may, however, serve in this respect as a fruitful complementary addition. In this contribution, the implementation of persistent identifiers on the existing ELPUB.scix.netbase is elaborated in detail. Furthermore, the authors present the result of efforts related to the harvesting of ELPUB-metadata and to the creation of a citation index. The paper concludes with an outlook on future plans.
