The Crossref Nominating Committee invites expressions of interest to join the Board of Directors of Crossref for the term starting in March 2024. The committee will gather responses from those interested and create the slate of candidates that our members will vote on in an election in September.
Expressions of interest will be due Monday, June 26th, 2023.
About the board elections The board is elected through the “one member, one vote” policy wherein every member organization of Crossref has a single vote to elect representatives to the Crossref board.
We were delighted to engage with over 200 community members in our latest Community update calls. We aimed to present a diverse selection of highlights on our progress and discuss your questions about participating in the Research Nexus. For those who didn’t get a chance to join us, I’ll briefly summarise the content of the sessions here and I invite you to join the conversations on the Community Forum.
You can take a look at the slides here and the recordings of the calls are available here.
We have some exciting news for fans of big batches of metadata: this year’s public data file is now available. Like in years past, we’ve wrapped up all of our metadata records into a single download for those who want to get started using all Crossref metadata records.
We’ve once again made this year’s public data file available via Academic Torrents, and in response to some feedback we’ve received from public data file users, we’ve taken a few additional steps to make accessing this 185 gb file a little easier.
In 2022, we flagged up some changes to Similarity Check, which were taking place in v2 of Turnitin’s iThenticate tool used by members participating in the service. We noted that further enhancements were planned, and want to highlight some changes that are coming very soon. These changes will affect functionality that is used by account administrators, and doesn’t affect the Similarity Reports themselves.
From Wednesday 3 May 2023, administrators of iThenticate v2 accounts will notice some changes to the interface and improvements to the Users, Groups, Integrations, Statistics and Paper Lookup sections.
1 September 2022 These 2017 guidelines are not changing but we’ve added a recommendation to improve accessibility for DOI links on landing pages. Please see our recent call for comments for more information. This page will be updated when the recommendation has been finalized.
Display guidelines for Crossref DOIs - effective from March 2017
It’s really important for consistency and usability that all members follow these guidelines. We rarely have to change them and usually only do so for very good reasons. Please note that this is for display of Crossref DOIs, not anyone else’s DOIs, as not all DOIs are made equal.
The goals of the guidelines are to:
Make it as easy as possible for users without technical knowledge to cut and paste or click to share Crossref DOIs (for example, using right-click to copy a URL).
Get users to recognize a Crossref DOI as both a persistent link as well as a persistent identifier, even if they don’t know what a DOI is.
Enable points 1 and 2 above by having all Crossref members display DOIs in a consistent way.
Enable robots and crawlers to recognize Crossref DOIs as URLs.
When linking to a research work, use its DOI rather than its URL. If the URL changes, the publisher will update the metadata in Crossref with the new URL, so that the DOI will always take you to the correct location of the work.
How to display a Crossref DOI
When displaying DOIs, it’s important to follow these display guidelines. Crossref DOIs should:
Crossref DOIs should be displayed as the full URL link wherever the bibliographic information about the content is displayed.
An obligation of membership is that Crossref DOIs must be displayed on members’ landing pages. We recommend that Crossref DOIs also be displayed or distributed in the following contexts:
Tables of contents
Full-text HTML and PDF articles, and other scholarly documents
Citation downloads to reference management systems
Metadata feeds to third parties
“How to Cite This” instructions on content pages
Social network links
Anywhere users are directed to a permanent, stable, or persistent link to the content.
Crossref members should not use proprietary, internal, or other non-DOI URLs in citation downloads, metadata feeds to third parties, nor in instructions to researchers on how to cite a document.
Crossref DOIs in reference lists and bibliographies
Linking references in journal articles using Crossref DOIs is a condition of membership. This means including the DOI for each item in your reference list. We strongly encourage members to link references for other content types too. Because there are space constraints even in online references lists, Crossref DOIs can be displayed in several ways, depending on the publisher’s preference and publication style. We recommend the following options:
use the Crossref DOI URL as the permanent link. Example: Soleimani N, Mohabati Mobarez A, Farhangi B. Cloning, expression and purification flagellar sheath adhesion of Helicobacter pylori in Escherichia coli host as a vaccination target. Clin Exp Vaccine Res. 2016 Jan;5(1):19-25. https://0-doi-org.libus.csd.mu.edu/10.7774/cevr.2016.5.1.19
display the text Crossref with a permanent DOI link behind the text. Example: Galli, S.J., and M. Tsai. 2010. Mast cells in allergy and infection: versatile effector and regulatory cells in innate and adaptive immunity. Eur. J. Immunol. 40:1843–1851. Crossref.
The International DOI Foundation created the ShortDOI service as an open system that creates shortcuts to DOIs. DOIs can be long, so this service aimed to to the same thing as URL shortening services. For example, for the DOI https://0-doi-org.libus.csd.mu.edu/10.7774/cevr.2016.5.1.1, the short form is https://0-doi-org.libus.csd.mu.edu/bwfc. Only one ShortDOI is created for each DOI, and the ShortDOI returns exactly the same results as the DOI. ShortDOIs are not widely used and are not really actual DOIs themselves, which is confusing. We recommend simply creating shorter DOIs in the first place. Learn more about constructing your DOIs.
Frequently Asked Questions (FAQs) about the March 2017 changes
Do we need to change how DOIs are displayed in already-published content and existing PDFs?
No - you can make the change for new content going forward and do not need to update existing PDF files. You can update existing content if you want to, but this is optional. The current form, for DOI links using http://dx.doi.org, will continue to work as long as Crossref and the DOI system exist.
Can we make the display changes now or do we need to wait?
These guidelines are now in effect. We set the date as March 2017, after giving our members six months’ notice to make the changes.
Why does the DOI have to be displayed as a link on the page that the DOI links to?
Some members have reported resistance from colleagues to displaying the Crossref DOI on the landing page as a link (they say the DOI link in that location appears superfluous as it appears to link to itself). The Crossref DOI must be displayed as a link, because it is both an identifier and a persistent link. It is easier for users when members display the DOI as a full link as they can copy it easily. Also, many users don’t know what a DOI is, but they know what a link is. We want to encourage the DOI to be used as a persistent link, and to be shared and used in other applications (such as reference management tools). A fully linked DOI enables this, wherever it appears.
Do we need to redeposit our metadata to update the DOI display?
No - there is no need to redeposit metadata. These guidelines cover how you display DOIs on your website, not how to register them with us.
Why not use doi: or DOI:?
When Crossref was founded in 2000, we recommended that DOIs be displayed in the format doi:10.NNNN/doisuffix and many members still use doi:[space][doinumber], DOI: [space][doinumber], or DOI[space][doinumber]. At the time that the DOI system was launched in the late 1990s it was thought that doi: would become native to browsers and automatically resolve DOIs, like http:. This did not happen, and so doc:/DOI: is not a valid way of displaying or linking DOIs.
Advantages to changing the display to a resolvable URL (even on the page the DOI itself resolves to) include:
A DOI is both a link and an identifier. Users will more easily recognize Crossref DOIs as an actionable link, regardless of whether they know about DOIs
Users who do not know how to right-click on the link and choose Copy link will still be able to easily copy the DOI URL
Machines and programs (such as bots) will recognize the DOI as a link, thereby increasing discoverability and usage.
What about reference formats in style guides (such as APA, Chicago) that use doi: [doinumber]?
A number of style guides recommend including a DOI in the reference as an unlinked string. We are contacting the main style guides to request that they update their recommendations for DOIs to use the full-URL form.
Why not use dx as in http://0-dx-doi-org.libus.csd.mu.edu/?
Originally the dx separated the DOI resolver from the International DOI Foundation (IDF) website but this changed a few years ago and the IDF recommends http://doi.org as the preferred form for the domain name in DOI URLs.
Why should we use HTTPS?
Providing the central linking infrastructure for scholarly publishing is something we take seriously. Because we form the connections between publisher content all over the web, it’s important that we do our bit to enable secure browsing from start to finish. In addition, HTTPS is now a ranking signal for Google, which gives sites using HTTPS a small ranking boost.
The process of enabling HTTPS on publisher sites will be a long one, and given the number of members we have, it may take a while before everyone’s made the transition. But by using HTTPS we are future-proofing scholarly linking on the web.
Some years ago we started the process of making our new services available exclusively over HTTPS. The Crossref Metadata API is HTTPS enabled, and Crossmark and our Assets CDN use HTTPS exclusively. In 2015 we collaborated with Wikipedia to make all of their DOI links HTTPS. We hope that we’ll start to see more of the scholarly publishing industry doing the same.
