  3. 3. Crossref makes research outputs easy to find, cite, link, assess, and reuse.
 We’re a not-for-profit membership organization that exists to make scholarly communications better. Mission
  4. 4. Our truths
  5. 5. Crossref overview • Over 12,000 member organizations • 16 member board, cross section of international publishers • Metadata store of over 100 million scholarly content items • A DOI is just the start - We offer a wide array of services to ensure that scholarly research metadata is registered, linked, and distributed. • We preserve the metadata we receive and make it available via our open APIs and Search.
  6. 6. Why do publishers join Crossref? • To help get their content discovered • Show people where their content is located and update that if/when the content moves • Drive more traffic to publications • Turn references into hyperlinks • Find out who is using their content • Participate in other collaborative services

  11. 11. Using metadata: who, why and how?
  12. 12. What do we mean when we talk about Crossref metadata?
  13. 13. Members —> Crossref Basic metadata: titles; author names; ISSNs/ ISBNs, abstracts, references Funding Information, Funder identifiers, award numbers License Information, License URIs Full-text URIs (e.g. for text mining and similarity check) Crossmark: updates, retractions, corrections ORCID iDs Recently: Peer Review reports, relations Soon… Organization IDs, Grant IDs…

  15. 15. Search & discover
  16. 16. Search & discover
  17. 17. Measure, report…
  18. 18. …and apply metrics
  19. 19. A collaborative writing tool Built a tool based on Crossref metadata to allow authors to search and cite without leaving the editor. Match & link citations
  20. 20. Aggregate and integrate content Help Unpaywall identify and disambiguate over 20 million Open Access articles, and it is absolutely essential to our work. We 😍 ❤ 🤗 Crossref! – Jason Priem, ImpactStory
  21. 21. Collect related research objects We check for the availability of articles associated with our data packages, and to verify some of our metadata. Being able to do this programmatically has revolutionized our data publication workflow. – Elizabeth Hull, Dryad
  22. 22. Fill metadata gaps We enrich the metadata of our hosted preprints and link them to the manuscript or version of record. We also perform various analyses regarding the completeness and discoverability of our records. – Mark Hahnel, Figshare
  23. 23. Verify records are valid and accurate Identify articles unambiguously as we preserve scholarly literature in our system. Also, in the rare instances when we ‘trigger’ journals for open access, we want the reference-linking functionality to work, and we work with Crossref to point the URLs to our site for resolution. – Craig van Dyck, CLOCKSS
  24. 24. author profiling tools
  25. 25. over 600 million metadata queries per month across all interfaces
  26. 26. Crossref REST API overview • Search, filter or sample metadata from thousands of members • Returns results in JSON • The information is continually updated • The REST API helps unlock the value metadata; making it available to query easily and to integrate into other tools and services • No sign-up is required and the data can be treated as facts from members. Therefore it is not subject to copyright and available to use for whatever purpose • Simplifies access for researchers who want to mine and analyze research outputs and content
  27. 27. Metadata API Plus ● Metadata ‘snapshots’ ● Metadata normalized across interfaces ● Priority support ● Guaranteed uptime ● Higher rate limit ● Notifications ● *Also has a free public interface
