  14. 14. Crossmark
  15. 15. Why is it important to update content? • Readers need to know that they can trust that they can use the research • Publishers and journals are the authority on this • Not bad/negative to update works - it helps to maintain the scholarly record - this is an important job for publishers to do
  16. 16. What’s the problem?
  17. 17. Updates are shown in different ways
  18. 18. It’s good to see updates in a consistent way
  19. 19. On HTML and PDF
  20. 20. Solution: Crossmark • An embedded button for HTML and PDF that, when clicked, shows the researcher publication information that a publisher chooses to include • A great way to show users extra or updated information about the content they’re viewing so that they can trust it • The information stays with the article and can be accessed even away from the publisher site • Machine-readable metadata available via the Crossref REST API
  21. 21. Uptake • Over 670 publishers depositing Crossmark metadata • For over 7.8 million DOIs • Around 1% are updates (so even more important that they’re flagged!) • Over 2,000 of the updates are retractions
  22. 22. Benefits • Lets readers know they can trust the content • Convenient - one place to access information • Works in both HTML and PDF • Easier for researchers to cite the most recent version of content • Free for researchers to click on • More dissemination of your metadata
  23. 23. How do to get started? • Sign up - • Create a Crossmark policy page and assign a DOI to it • Deposit Crossmark metadata • Record DOI in the metadata of your HTML landing page • Display the link and Crossmark logo on your HTML and PDF • Keep your Crossmark content up to date

  25. 25. What is Similarity Check? Our Similarity Check service offers publishers with a way to actively engage in efforts to prevent plagiarism. Members are provided with access to Turnitin’s powerful text comparison tool, iThenticate. This allows them to compare their own documents against the largest comparison database of scientific, technical and medical content in the world. Similarity Check members contribute their own published content into iThenticate’s database of full-text literature.

  27. 27. How the service works • Upload a document to iThenticate • A similarity report is produced • Compare side-by-side • Editor makes a decision about whether the similarity detected is legitimate or if further investigation is required • When members publish new content, they provide a link to their full-text which Turnitin use to index the item and add it into their database
