Navigating the website and getting started with membership Some additional services How to get help Keep in touch
Thank you for letting us join you virtually today.
My name is Vanessa, I’ve been at Crossref for 3 years now and my role is Community Outreach Manager. I manage our LIVE local events both online and in-person when we are able to again, get feedback and input from our community around the world, webinars, and the Crossref ambassador programme. Prior to Crossref I worked in International Development with a focus on access to scholarly information and scientific research in developing countries.
With me today is Rachael Lammey, Rachael is Head of Community Outreach, she previously worked in publishing before joining Crossref in 2012. At Crossref she has worked in Product Management, managing our Similarity Check service, before moving over to the Community Outreach team in 2016.
Today we will be talking to you about Crossref’s mission and purpose, how to find your way on our website and giving an overview of some of our additional services. Last week we held two webinars on why Crossref DOIs are important and how to manage your metadata at Crossref, if you missed these sessions will we will be sharing the recording, slides and Q&A from these sessions soon so you’ll be able to catch up.
This is our mission at Crossref (slide) Over 16,000 member organizations 40 staff based in USA, UK, Ireland, France and Germany. 16 member board, cross section of international publishers Metadata store of over 116 million scholarly content items A DOI is just the start - We offer a wide array of services to ensure that scholarly research metadata is registered, linked, and distributed. We preserve the metadata we receive and make it available via our open APIs and Search.
You can find everything you need to know on our website. Let’s take a look at where things are.
Apply - What you need to know before you become a member (become a member page) Membership form Members - members page with info on getting started, member obligations, DOI display guidelines and links to managing your deposits and pay your invoices. Content Registration Services Education Curriculum - example content reg methods, contact us for questions if cannot find the answer Fees page Search interface Events/webinars page
These are our services at Crossref
Reference linking means hyperlinking to Crossref DOIs when you create your citation list.
This makes it possible for readers to follow a DOI link from the reference list of a published work to the location of the full-text document on a member’s publishing platform, building a network infrastructure that enhances scholarly communications on the web, because DOI links don’t break over time. Publishers used to sign individual agreements between each other to agree to link to each other’s content. This wasn’t sustainable as publishing grew, so Crossref was formed to provide a central solution.
Reference linking is an obligation for Crossref members. If you’re a member you should be linking your reference lists using DOIs (where there are DOIs available).
You can see this example from PeerJ - if you hover over the link in the reference list, you can see that the link is being made by the DOI.
Reference linking is accomplished by members and their production teams, with the assistance of authors and editors who add the links to each reference in their articles. You can ask your authors to add DOIs to their reference lists or add this at copyediting stage.
There are a number of ways to add DOIs to references including searching via a search engine, which is easy but slow, querying Crossref API with XML which is very efficient but requires some skill, we also have our own look up tools which I’ll show you in the next slide, we have a content registration system that Rachael will talk more about and also some third party tools enable this such as OJS which has launched an updated plug-in which includes reference deposits, and at Crossref, our new Metadata Manager tool will help link and deposit references.
A good next step, once you are linking your references, is to look into participating in our Cited-by service.
It’s kind of like the reverse of reference linking as it lets members show authors and readers what other Crossref content is citing their content. You ask Crossref for this information, and then we allow you to display it on your website in any format you like.
You can see an example of Cited-by on the slide. By clicking on the list of Cited-by matches, you can then see items that have gone forward to reference the article you are reading, perhaps helping you to find more relevant research.
There are many online citation indexing services and databases but what is different about Cited-by is that it lets our members display the Cited-by links on their content on their own website in any way they wish. It also only counts the citations we can see in Crossref, so this may differ from other citation ‘scores’ as they are looking at a different set of data.
This benefits the readers of the content because they can get a sense of how often the content has been cited and can easily click the links to go to the citing content. How often something is cited can also be useful information for publishers, authors, research institutions and funders.
Once your account has been enabled for Cited-by (email our membership team to do this), you can then ask, or query Crossref for the articles that we can see that are citing your content. The simplest way to do this is to log into the admin system at doi.crossref.org and enter the DOI that you want to query. This will return a list of the other articles citing it.
For XML users, you can query by uploading XML files to our deposit system and we will return a list of the matched citations.
At the time of me putting together this presentation we could see over 1 billion cited-by links! (1,069,963,353)
RL take over. Similarly Check is a service that helps editors prevent plagiarism. To do this, our members are given access to Turnitin’s powerful text comparison tool, called iThenticate, so that they can compare their own manuscripts against the largest comparison database of full-text academic content in the world.
While there are several plagiarism screening tools available, using iThenticate as a Similarity Check member is unique as it creates a relationship between content-owners and Turnitin. Similarity Check members have a reduced fee for the use of iThenticate because they contribute their own published content into Turnitin’s database of full-text literature. This means that as the number of Similarity Check members grow, so too does the size of the iThenticate content database. More content in the database, means greater peace of mind for editors looking to determine a manuscript’s originality.
To use the service if you’re a Similarity Check member:
Users upload a document to iThenticate. Manuscripts can be submitted in a number of formats, including Word, text, PDF, and HTML .
A similarity report is produced, which shows the percentage of similarity between a the submitted manuscript and content existing in the database.
Users then compare the original and database documents side-by-side
Editor can then make a decision about whether the similarity detected is legitimate or if further investigation is required
When Crossref members register new content, they provide a link to their full-text which Turnitin use to index the item and add it into their database, so the database is constantly expanding and kept up-to-date. Here is an example of a Similarity report. It shows the percentage of text that is similar between the submitted document and those found in the database. Editors can review the match and click for more information. However, the similarity percentage can be misleading if not interpreted properly. Some text may be similar, such as properly cited references or standard scientific descriptions, for example the Materials and Methods used in an experiment or research.
Users can exclude certain sections of text or sources or set a percentage threshold.
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
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.
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 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 is an example with an update. Clicking on the Crossmark button shows that this article had a correction made to the original version. Readers may click on the link to view further information. Encourage sharing of that information as a valuable service that publishers provide to help anyone reading the work know what they can and can’t trust.
This year we also launched the ‘Community at Crossref’. This is an open, online space for members where they can start a discussion, or get a question answered by the Crossref team or by another Crossref member. It allows members to discuss in their own local languages and with others working in similar settings, share tips and advice, hear about upcoming news from Crossref and more widely within the industry. It could also provide scope for participation in beta-testing or other ways for our members to contribute to developments at Crossref and to provide feedback.
We’ll put questions we can’t get to in here in the coming week.

How to add Crossref DOI links to references
• Use a search engine for individual articles (slow)
• Query Crossref with XML (efficient, requires skill)
• Use Crossref lookup tools (simple) -
• Use Metadata Manager
• Third party tools such as OJS 3.1.2
Cited-by provides a clear overview of
the publications that have cited a piece
of content - and lets your readers
navigate from your content to the
content that is citing it.
Querying for Cited-by links
Our Similarity Check service offers publishers with a way to actively engage in efforts to
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.
There are additional fees associated with this service, and members have to fulfil certain
criteria to qualify for it.
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. There is no magic number!
• 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
•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
•From 2020, we have removed the charges for participation in this service
The Crossmark button gives readers quick and easy access to the current status of an item of
content, including any corrections, retractions, or updates to that record.
