4. Reference Linking

5. Reference Linking
• Members must add outbound
Crossref DOI links to their
references
• Publishers used to make these
agreements individually
• Membership of Crossref
provides social and technical
infrastructure to make sure
research is linked persistently
• Required only for current journal
content but encouraged for all

6. How to add Crossref DOI links to references
• Ask the authors to add DOIs to their reference
lists in your author guidelines
• Add at copyediting stage
• Use a search engine for individual articles (slow)
• Query Crossref with XML (efficient, requires skill)
• Use Crossref lookup tools (simple)

7. Crossref can
see over
805,713,223
Cited-by links
Cited-By

9. How to participate
1. Deposit reference lists with Crossref for your journal
2. Email member@crossref.org to sign-up
3. Query Crossref for a list of all DOIs citing a document
4. Display Cited-by results on your website
No fee - Cited-by is an optional service

14. Use Event Data to…
Funders can use Event Data to isolate and track the dissemination and usage of the
research they funded
Build a reading recommendation tool for researchers by using Event Data to analyse
co-citations in Wikipedia
Publishers can undertake metric-lead analysis to help drive business needs
Notify an organization that their research is trending
Researchers can analyze data from blogs and social media to help with preprint
discoverability and impact analysis
Publishing service providers can feed Event Data in their usage or altmetrics
dashboards or visualisations

15. Crossmark

16. 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

17. What’s the
problem?

18. Updates are shown
in different ways

21. It’s good to see
updates in a consistent
way

22. On HTML and
PDF

23. 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

28. 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

29. 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

30. How do to get started?
• Sign up - member@crossref.org
• 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

31. Similarity Check

32. 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.

33. • Turnitin’s plagiarism detection
software
• Text-based screening
• Contains content indexed from over
1 billion web pages, 57 million items
from Crossref members, and a
further 105 million items from other
content partners such as Pearson,
Cengage, EBSCOHost etc.
What is iThenticate?

34. 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

35. Similarity report

36. Who’s using Similarity Check?
Over 1,300 participating Crossref members
Average 405,209 manuscripts screened every month this year
Increase in usage from publishers in Japan, Brazil, South Korea and Turkey
Publishers are putting more time and effort into their plagiarism policies
• resources (staff and time)
• cost
• workflow
• education
• follow-up action

37. Doc-to-doc comparison
• Doc-to-doc comparison allows
users to upload one primary
document and compare it
against up to five other
documents.

38. Doc-to-doc comparison

39. What issues are publishers looking for
• Poor, missing, or incomplete references (can be fixed)
• Self-plagiarism/text recycling (can be fixed)
• Unattributed use of parts of another person’s work
• Submitting another person’s work as your own
• Is the author attempting to mislead/misrepresent?

40. Who can join Similarity Check?
• Open to Crossref Publisher members in good standing
and who are actively assigning article-level DOIs to their
content.
• Publisher’s DOI metadata must include a URL in the
<iparadigms> field which points to their full-text HTML,
PDF or plain text content.

41. How to join

42. How much does it cost?
• Annual administrative fee equal to 20% of your Crossref
membership fee, paid to Crossref
• Per-document upload fee, paid directly to Turnitin
