Repositories – websites enable long-term, structured storage and sharing of digital documents.

The following types of repositories can be distinguished:

  • domain repositories - collect materials related to a specific field of knowledge,
  • institutional repositories - collect the scientific achievements of a given institution, e.g. university - they collect articles, scientific dissertations, lectures, and other materials archived by university employees,
  • research data repositories - contain raw and processed research data from various fields of knowledge,
  • general purpose repositories.

Examples of repositories:

  • Zenodo – an open-access, interdisciplinary repository created by OpenAIRE and CERN for storing various types of data from each subject area.

When looking for the right repository, both for sharing and searching for research data, it is worth using the repository registry.

Services that allow you to search for repositories:

  • OpenDOAR (Directory of Open Access Repositories) is a directory of open repositories of scientific institutions. The portal indexes the resources of several thousand repositories and allows you to search them (search engine),
  • - an international registry of research data repositories from all disciplines, which allows you to browse the list of data repositories broken down by type, domain, and country,
  • ROAR (Registry of Open Access Repositories) - registry of open access repositories created at the University of Southampton,
  • Open Archives - a list of repositories and digital libraries from around the world together with descriptions and links,
  • - open access repository of the American Cornell University in the fields of physics, mathematics, computer science, electrical engineering, statistics, finance, and economics.
