CrossRef DOI Resolver

Digital Object Idenfiers (DOI) are a persistent identifier strategy used by around 3,000 publishers to identify their documents: mostly scholarly publications. An example of a DOI is


which identifies:

Watson JD, Crick FH (April 1953). "Molecular structure of nucleic acids; a structure for deoxyribose nucleic acid" (PDF). Nature 171 (4356): 737?738.

CrossRef maintains one of the largest DOI registries, and has minted URLs for every DOI they manage. For example the DOI above can also be expressed as the URL:

When resolved this URL will redirect to the publisher's page for the document that is identified. The service will content negotiate to make available alternate representations of the citation metadata:

  • application/rdf+xml
  • text/turtle
  • application/atom+xml
  • application/unixref+xml (CrossRef's homegrown XML format)

For example:

curl --location --header "Accept: application/rdf+xml"

Detailed information about journals, pages, authors can be found in the data, as well as links to journals in the Linked Periodicals dataset. More about the service can be found on a CrossRef blog post.
