Note

This documentation site is still a work in progress. We are in the process of completing the missing parts.

CDS (CERN Document Server) is the CERN Institutional Repository. It preserves and disseminates CERN's research outputs — including publications, software, datasets, departmental documents, and multimedia materials — ensuring their long-term accessibility.

In a nutshell

CDS is the place to archive your final, official documents that need to be preserved for the long term. When you deposit a document in CDS, it becomes part of CERN's permanent record and will be retained for the lifetime of the Organization.

Deposits can be made public or restricted to specific audiences (e.g. CERN users only).

Record deletion

Once a record is published, it cannot be deleted. A short grace period is available to correct mistakes. See our Content Policy for details.

Permitted content

You can find detailed guidance in our Content Policy, but in general CDS is intended for:

  • Final versions of CERN research publications
  • Datasets and software releases
  • Departmental and administrative documents meant for long-term preservation
  • Official multimedia (e.g. photos)

Other content

CDS is not the right place for:

  • Personal documents or multimedia
  • Work-in-progress materials or drafts
  • Temporary files or items not meant for archival preservation

For such content, evaluate using CERNBox instead.
