We offer a wide array of services to ensure that scholarly research metadata is registered, linked, and distributed. When members register their content with us, we collect both bibliographic and non-bibliographic metadata. We process it so that connections can be made between publications, people, organizations, and other associated outputs. We preserve the metadata we receive for the scholarly record. We also make it available across a range of interfaces and formats so that the community can use it and build tools with it.
Some of our services are only available to members - most of these services are included your membership but some involve an extra fee (marked *). We also offer a range of services free of charge to the scholarly community, with the option of premium service versions at an extra charge (marked ~).

Register
Rich metadata leads to greater discoverability
The more complete the metadata registered, the more accurate the view of the scholarly record and the more discoverable the content is to the scholarly community.
Through our content registration service, members register and maintain metadata for their content. We are interested in the full range of metadata for each publication, including information on:
- contributors (such as authors, editors, reviewers)
- funding (such as funding body, grant number)
- publication history (such as versions, updates, revisions, corrections, retractions, dates)
- peer review (such as status, type, reviews)
- access indicators (such as publication license, text & data mining URLs, machine mining URLs)
- related resources & associated research artifacts (such as preprints, figures & tables, datasets, software, protocols, research resource IDs).
Unique identifiers for authors, organizations, and associated scholarly outputs enhance precision and quality, members can deposit accurate funder acknowledgment metadata when they apply the unique funder identifier in Crossref’s Funder Registry service, a regularly updated, industry-standard taxonomy of grant-giving organizations.
Link
Linking improves the scholarly enterprise
The complete set of scholarly links spans time, geography, and disciplinary boundaries.
We connect all the metadata elements we can accurately identify, from all phases of publication, across content records in our vast corpus. We link literature to people, literature to resources and associated research artifacts, and soon, literature to the activity surrounding the publication. Amongst the vast web of links, we connect research output content to external tools such as Turnitin’s iThenticate in the Similarity Check service, assisting members in plagiarism detection. With the references deposited by members, Crossref offers a Cited-by service so that participating members can discover all the publications that have cited their content. The upcoming Event Data service will offer links between literature and various platforms where it is shared, discussed, mentioned, referenced, reviewed, and considered.
Retrieve
Metadata is meant to be used
Crossref delivers metadata to systems throughout scholarly communications making content easy to find, cite, link, assess, and reuse.
Our metadata retrieval service supports a diverse range of systems by offering a wide range of formats and interfaces. We do this because the range of organizations who use it – from publishers to libraries, to funders to startups–and how they use it, are diverse. Using metadata facilitates content discoverability–if it’s rich metadata, all the better. Crossmark is a powerful example: Metadata is displayed on publication landing pages through the a widget that gives readers quick and easy access to the current status of an item of content. With one click, readers can see if content has been updated, corrected or retracted and access additional metadata provided by the member.
