To combat the challenges posed by the many versions of a same article that can exist on the web, Elsevier and other publishers have banded together with CrossRef to create the CrossMark identification service

One of the challenges researchers face is a lack of clarity around whether they are consulting the most up-to-date version of an article or research.

Despite even the most careful scrutiny during the publishing process, corrections, updates and errata, as well as retractions and withdrawals, are sometimes still necessary. The challenge is that many versions of the article may still exist out on the web.

To combat this problem, Elsevier and other publishers have banded together with CrossRef to create the CrossMark identification service. By clicking on the CrossMark logos in online PDF or HTML documents, readers can quickly learn the current status of a document.  If the one they have opened is not the most up-to-date, the logo will help them to navigate to the most recent version available.

Elsevier and other publishers will display the new logo on journal content that has been assigned a CrossRef DOI. It will only appear on final published versions, not on Articles in Press.

Readers simply need to click on the logo and, if they are connected to the internet, a pop-up box will appear showing the current status of the document. This will work whether the reader is on the publisher's website, a third-party site or is viewing a PDF downloaded at an earlier date.


The most common pop-up will be the message that the document is still current. Occasionally, however, readers will discover that the document has updates and a CrossRef DOI will link to the update on the publisher's site.

Often, copies of documents are posted on a variety of sites which can make it more difficult for the publisher to notify readers when a correction or other change materially affects the interpretation of the work. CrossMark can help with that communication.

We are aiming to roll this service out to 1,250 of our 2,000 journals by the end of 2012 and eventually to all Elsevier titles.

Egbert van Wezenbeek, Director Publication Process Development, has been responsible for leading the CrossMark project at Elsevier. He commented: "The launch of CrossMark offers a significant benefit to researchers. Not only does it create a standard across scholarly publishing for recognizing changes, it can also highlight important publication record information. This can include publication history, the location of supplementary data, access policies, funding sources, peer review processes and other useful information."
