Vanessa Fairhurst presents about managing changes to scholarly content using the Crossmark service. Presented at Crossref LIVE local events Pretoria and Cape Town, 17th and 19th April 2018.

1. Managing
changes to
content

2. 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

3. What’s the
problem?

4. Updates are shown
in different ways

6. Examples

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

9. On HTML and
PDF

10. 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

15. Uptake
• Over 550 publishers depositing Crossmark metadata
• For over 6.5 million DOIs
• Around 1% are updates (so even more important
that they’re flagged!)
• Over 2,000 of the updates are retractions

16. 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
• Additional publication information all in one place
• Free for researchers to click on
• More dissemination of your metadata

17. How do to get started?
• Sign up
• Create a Crossmark policy page and deposit an identifier
• 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
