After it’s published content changes quite frequently and readers need to know. It could be an update or a correction which are quite common but more retractions have been reported and sometimes articles need to be withdrawn.
Not sure if anyone is familiar with retraction watch blog, it’s an interesting blog that reports on retracted papers.
Publishers needed an easy way to communicate those changes to the readers. We are a membership association of publishers, publishers asked us to develop a solution. So in 2012 after a lengthy pilot we launched CrossMark launched.
This is an example of a correction notice on a publisher article.
This one is at the top - other publishers may choose to place it elsewhere so there is no consistent way of seeing the correction across publishers.
Hard to find and hard to track.
Wouldn’t travel with PDF
So that you don’t miss them! Confidence in content.
So what is CrossMark?
So as I’m sure you have heard throughout the morning- Crossref is all about either metadata in or metadata out and CrossMark is a great example of both. Publishers deposit extra metadata that they want CrossMark to display and researchers can then access this data though the widget or through the Rest API.
Now I’m going to show a few examples of Crossmark
So what are some of the things that make Crossmark great.
This is an example of a CrossMark with no updates.
The document is current.It displays a link to the publisher maintained version which in this case is current.
Below you can see the additional publication information.
Here’s another example where there are updates available and this is the
Funding data A standard way of reporting funding sources for published scholarly research Important because funding bodies cannot easily track the published output of their funding. Certain publishers need to comply with government mandates such as the OSTP that call for access to scientific journal articles from publicly funded research. We have a Open Funder Registry with more than 12,000 funder names and IDs and we encourage publishers to include funding data whenever possible ORCIDS persistent identifiers for researchers. It’s a great way to keep track of who contributed to what work and for
License information is important for the purposes of text and data mining for example
Most recently Clinical trial information links articles associated with one clinical trial together
Showing funding data information.
Managing changes to content: Crossmark
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
• 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
• 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
• Additional publication information all in one place
• Free for researchers to click on
• More dissemination of your metadata
• Nearly 500 publishers depositing Crossmark
• For over 5m DOIs
• Around 1% are updates (so even more important that
• Over 1600 of the updates are retractions
What information can you include?
• Funding data
• License information
• Clinical trial information
• Other information (up to the publisher)
• Content changes and readers need to know
• An easy way to communicate publication information
and changes to researchers
• The more metadata you register the richer & more
useful your content becomes
How do to get started?

• Deposit Crossmark metadata
• Record DOI in the metadata of your HTML landing page
• Display the link and Crossmark logo on your HTML and
• Keep your Crossmark content up to date
