As 2013 comes to a close and CrossRef approaches the 14th anniversary of its founding I’m very happy to report that things are in great shape. Steady growth continues across the board with participating publishers now over 4,700, the number of content items approaching 65 million, the number of manuscripts run through CrossCheck is over 100,000 per month and new services like CrossMark and FundRef starting to take off. FundRef is particularly interesting because it’s something that was developed in 2012 and launched in 2013 and is now proving to be a key piece of infrastructure for both CHORUS and SHARE. Below you'll also read about archiving, which was discussed during our annual meeting and is very important to our membership.
CrossRef’s text and data mining service was just approved by the board at its November meeting. The service is scheduled to roll out in early 2014 and information about the Pilot, which was named Prospect, is now available. There are two main aspects of the service: 1) a common text and data mining (TDM) API that enables researchers to request full text content from publisher sites in a standard way and 2) a terms and conditions library for those publishers who want to ask for researchers to agree to additional TDM terms. The terms and conditions library isn’t required for OA content or where publishers allow TDM by researchers at subscribing institutions.
I’ll finish by wishing everyone a happy New Year.
A couple of years ago CrossRef revised its DOI display guidelines to display CrossRef DOIs as full URLs. To create a DOI URL, anyone can simply prepend http://dx.doi.org/ to any DOI. Below are examples of DOIs displayed in the recommended or best practice way on journal article landing pages and on the FundRef search results page.
Below is an example form Sri Lanka Journals Online. The CrossRef DOI is displayed as a URL on the Anuradhapura Medical Journal article landing page.
Another example of the CrossRef DOI displayed as a URL on this AIP Physics of Plasmas article landing page.
And an example of CrossRef DOIs displayed in the correct format on the FundRef Search results page.
FundRef, the funder identification service, has seen a healthy uptake since its launch in May. Out of the 28 publishers already participating, 11 are depositing funding data to CrossRef. As of November 2013 we have 45,900 CrossRef DOIs with funding data.
FundRef allows publisher members to deposit funding data with (or after) the metadata they already provide to CrossRef for reference linking.
The data is available to funding organizations, publishers, libraries, research institutions, scholars, authors, and the public through CrossRef’s free search services (like FundRef Search and CrossRef Metadata Search) and application programming interfaces (APIs). It is also available to members and affiliates through XML queries and CrossRef Metadata Services data distribution channels.
Publisher members are encouraged to sign up.
CrossCheck now has over 530 publisher members, and content is now being added to the database from the Royal Society of Chemistry (RSC) and the Institution of Engineering and Technology (IET). iThenticate usage continues to grow alongside this, and CrossCheck publishers uploaded 100,000 documents to the system inboth August and October 2013.
CrossMark logos have now been deposited for over 300,000 CrossRef DOIs as more publishers sign-up and implement the service. Nearly 400,000 views of CrossMark information have been recorded from people clicking on CrossMark logos displayed on both HTML and PDF documents.
The current CrossRef membership agreement that requires all members to use commercially reasonable efforts to establish and maintain arrangements with archiving providers in the event that the Member no longer makes the content available. Why does CrossRef require this? To ensure the persistence of CrossRef DOIs.
The DOI technology built on the CNRI handle system is only one piece of the persistence puzzle. An equally important piece is the social contract that all members agree to. Members must keep their content available and the URLs registered at CrossRef up to date. Regardless of how good or stable CrossRef’s systems are or the DOI Handle system is, if members do not meet these social obligations, CrossRef DOI links break, and persistence of the scholarly record fails.
We know that occasionally journals go out of business or cease publication or go offline due to natural disasters. Archiving keeps those links active and allows the content to be accessible in those cases.
At CrossRef’s Annual Meeting on November 13, representatives from two archiving service providers, Randy Kiefer of CLOCKSS, and Kate Wittenberg of Portico, explained what archiving is (and is not) and why it is important.
Briefly, archiving is not
So that leaves the following criteria to have a true archiving solution that ensures persistence for the scholarly record:
Currently, the only archiving providers that actively maintain CrossRef DOI links to such triggered content are CLOCKSS and Portico. CrossRef is open to working with other providers. If you are providing archiving services for electronic content, or if you can recommend organizations that CrossRef should be working with to expand the number of members that meet this important requirement, please let us know at email@example.com. We'll be happy to add your organization to our archiving providers page.
And if content that you are maintaining at CrossRef encounters some kind of trigger event like a halt in publication, or a transfer of ownership, please alert firstname.lastname@example.org, so we can work with all parties to make sure CrossRef DOI links from references, bibliographic services, and other places continue work.
You may wish to consult The Keepers Registry for more examples of archiving providers and a directory of content that is being archived.
In recent months we've made some schema changes to deposit schema that will allow publishers to deposit additional or enhanced metadata. All schema versions from 4.3.0 on are backwards compatible and valid for current deposits. Deposit schema details are available in the help documentation.
Schema version 4.3.3:
Schema version 4.3.2:
Title Transfers for 2014
If you have acquired or sold a publication title for 2014, please notify CrossRef Support (email@example.com) of the transfer in advance to ensure a smooth transition. Title transfer procedures are available in our help documentation.
Note that DOIs already assigned by any previous title owner must be maintained, and new DOIs should not be created for existing content. DOIs for titles are available through the depositor reports. We are also able to provide DOIs and metadata for acquired titles upon request.
CrossRef offers Enhanced CrossRef Metadata Services (CMS) to both members and non-members (Affiliates). Enhanced CMS users can harvest metadata from CrossRef and use it in their systems according to the CMS license agreement which promotes linking to publisher full text by using CrossRef DOIs. The metadata CrossRef makes available is the standard bibliographic metadata, DOIs and references as deposited for Cited-by Linking.
IMPORTANT: Please remember that full text is not included as it are not part of the CrossRef metadata deposit. Abstracts may be included, but only if you deposit them as part of your metadata. This abstract function is still being tested.
Publisher members may chose whether each Enhanced CMS recipient can get the publisher’s metadata. CrossRef sends an email message to member business contacts when a new Enhanced CMS affiliate applies. That message provides the opportunity for members to exclude all of their metadata or just their reference metadata if they have it for that Enhanced CMS applicant. (Please note that these email messages come from Constant Contact.) If you are the business contact for a publisher, please do not opt out of Constant Contact email messages, or you may miss important notifications, and let us know promptly if your business or technical contacts change.) Members who want to verify whether have previously restricted access or not should contact Susan Collins.

The 2013 CrossRef Annual Meeting and Workshops in Cambridge, MA were a great success. With 150 attendees, we had the largest turnout of all of our annual meetings to date.
Heather Piwowar, co-founder of Impactstory, delivered the keynote presentation entitled "Building skyscrapers with our scholarship". She spoke about how data is making it possible for developers to build upon scholarship, enabling them to build structures "skyscrapers" and thus altering the "skyline" of research.
Other compelling speakers included: Kristen Fisher Ratan of PLOS, who spoke about agile/responsive publishing, Walter Warnick of OSTI who gave an update on OSTP, FundRef and CHORUS from a federal government perspective and a panel presentation from archiving providers Randy Kiefer of CLOCKSS and Kate Wittenberg of Portico. (See the archiving story above for a summary.)
The CrossRef Workshops preceded the annual meeting and covered technical, operational and workflow issues related to CrossRef.
The links to slides have been posted to the meeting agenda pages and links to the video recordings will be available soon.
This year we streamed the meeting live for the first time. Hundreds of people in the CrossRef community unable to attend in person were able to participate remotely.
Save the date for next year's CrossRef Annual Meeting - November 11-12, 2014 at the Royal Society in London, UK.
Kirsty Meddings and Carol Anne Meyer have reached their 5-year anniversaries with CrossRef. Congratulations to both.
Joe Wass joined CrossRef's Oxford office in August as our new R&D Developer, and Lindsay Russell joined CrossRef's Lynnfield office in October as Payroll and Benefits Administrator. Welcome Joe and Lindsay.
The CrossRef Board of Directors have finalized the fees for 2014. No changes to existing deposit or annual fees have be made. For the current fees, please visit the Member fees page.
We issued annual fee invoices for 2014 (dated 1/1/2014) on December 9th, if you haven’t received them by December 13th, please let us know.
Just a reminder, we bill membership fees annually, and deposit fees quarterly. The 4th quarter deposit invoices will be sent shortly after quarter (and year end) close. You should receive them the first week of January 2014.
Our payment terms are net 45. We have automated reminders and notices that are sent to you when invoices are due and past due. Please pay your bills promptly so that your access to the system is not interrupted.
It’s important to update your billing contact information with us as well so that you don’t miss any invoices or reminders.
The CrossRef Board of Directors tracks the set of statistics in the table above since they are key metrics of success for the CrossRef System. The number of queries (references sent to CrossRef to find the DOI to create permanent links to the content) for first three quarters of 2013 were at 684 million and went down by 15% from the same period last year. The number of references submitted that matched a DOI in the CrossRef System increased to 309 million from 285 (in the same period of 2012). Total deposits increased, with current increasing by 34% and backfile slightly decreasing. The number of members and the amount of content in the system continues to grow at a steady rate.
The table above is from the 3rd quarter of 2013 operating report. Expenses and revenues for the 3rd quarter are slightly under budget.
