The Crossref Curriculum

Introduction to content types

We store metadata and DOIs for many types of research-related content, and we currently accept these content types:

  • Books, chapters, and reference works: book title and/or chapter-level records. Books can be registered as a monograph, series, or set.
  • Conference proceedings: information about a single conference and records for each conference paper/proceeding.
  • Datasets: includes database records or collections. Registering datasets? Learn more about whether Crossref or DataCite is right for your needs.
  • Dissertations: includes single dissertations and theses, but not collections.
  • Grants: grants include both direct funding, and other types of financial support, such as the use of equipment and facilities. Registering a grant includes assigning it a DOI (or grant ID), which can be referenced in all resulting research activities, linking funding with outputs.
  • Journals and journal articles: at the journal title and article level, and includes supplemental materials.
  • Peer reviews: any number of reviews, reports, or comments attached to an associated article.
  • Preprints: includes preprints, eprints, working papers, reports, and other types of content that has been posted but not formally published.
  • Reports and working papers: this includes content that is formally published and is published with an ISSN or ISBN.
  • Standards: includes publications from Standards Development Organizations and Standards Setting Organizations.
  • It is also possible to create a DOI for a pending publication by depositing metadata before the content is made available.
  • If you have a content type that isn’t listed, please contact us.

You can also establish relationships between different research objects (such as preprints, translations, and datasets) in your metadata.
