A repository can be compared to an online archive which collects, preserves, and disseminates specific content. This content can either be related to a specific subject, for example collecting all scientific papers related to high energy physics, or collecting the entire intellectual output of an institution – for example CDS is CERN’s institutional repository. It collects a large variety of documents and resources (e.g. presentations, administrative notes, conference contributions, theses, posters, photos, videos, monographs, preprints, journal articles etc.) in order to provide access to them within, as well as in some cases outside of the institution. The Operational Circular no. 6 requires every CERN Author to submit a copy of their scientific documents to the CERN Document Server (CDS).
