July 2013

Ed PentzFrom the Executive Director

As usual there is a lot to report so I wanted to highlight a few important things. FundRef launched at the end of May and has received a lot of attention because it is well timed to play a role in connecting funding with publications in a transparent and open way. On July 18th CrossRef issued a news release that addresses how CrossRef will be moving forward with working with different organizations and initiatives around the world that might want to use FundRef. As part of the FundRef Pilot CrossRef organized a very productive collaboration with publishers and funders and so we are keeping that going with a FundRef Advisory Group made up of member publishers and funders to help guide FundRef developments.

CrossRef staff will be out and about at many different meetings over the next few months (see below) and I’m particularly looking forward to the Frankfurt Book Fair – we’d love to meet with publishers there and provide updates on all of CrossRef’s projects and services. I’m happy to say that registration is open for the CrossRef Workshop Day and Annual Meeting taking place on November 12th & 13th in Cambridge, MA, US. The agendas for both days look great. 

Finally, to keep up-to-date please take a look at the extensive range of webinars that are being run about CrossRef stuff.

DOIs in Use

An increasing number of CrossRef DOIs are assigned to data sets and components. CrossRef has assigned more than 1 million DOIs to this type of content. See several different examples below.

Below is an example from Standards in Genomic Sciences.

FundRef Update

FundRef, the funder identification service, launched in May. The new initiative--a result of collaboration between funding agencies and publishers is now available for publishers to deposit funding data. CrossRef publisher members participating in FundRef may add funding data to the bibliographic metadata they already provide to CrossRef for reference linking. FundRef data includes the name of the funder, a funder ID, and, optionally, a grant or award number. fundref logo

Manuscript tracking systems have plans to incorporate the FundRef Registry, a taxonomy of 4000 global funder names, into author submission systems. This will allow authors to choose from this controlled vocabulary to attribute funding sources in a standardized way. Publishers can then capture this data in their production systems to make the deposits in CrossRef for published manuscripts. We encourage interested publishers to contact their manuscript tracking and production providers to let them know they are interested in seeing these developments as soon as possible.

FundRef data is freely available to funding organizations, publishers, libraries, research institutions, scholars, authors, and the public through search services, application programming interfaces (APIs), XML queries, and data distribution channels. CrossRef provides end users with the following tools to enable them to search the funder metadata and look up the list of funders:

FundRef Search (beta) is a tool that allows the public to search FundRef metadata records deposited during the pilot phase of FundRef in 2012-2013. FundRef search can find records representing all of the funding bodies that were part of the pilot plus additional data from publishers that have joined FundRef since the launch.  As more publishers join FundRef, FundRef search will return additional results.

You may also see a list of funders in the
FundRef Registry . It’s a taxonomy of 4000 funder names, abbreviations, and alternate names, which was donated by Elsevier. This controlled vocabulary is freely available and can be incorporated into manuscript submission systems. 

The FundRef service was preceded by the FundRef pilot, which ran from Feb 2012 to Feb 2013.  The pilot participants included: 

American Institute of Physics (AIP)
American Psychological Association (APA)
Elsevier Science
Nature Publishing Group
Oxford University Press

US Department of Energy
US National Aeronautics and Space Administration (NASA)
US National Science Foundation
Wellcome Trust

Current FundRef members include:
American Institute of Physics (AIP)
American Psychological Association (APA)
Hindawi Publishing Corporation
Internet Medical Publishing
International Union of Crystallography (IUCr)
Journal of Rehabilitation Research and Development (JRRD)
Kowsar Medical Institute
Optical Society of America (OSA)

Publisher members are encouraged to sign up. In addition, extensions are planned to support emerging public access projects.

For more information, please see the following news release.  Or, join the next webinar or read additional news and articles about FundRef here. More information about FundRef can be found on the FundRef page.

CrossCheck adds new members, features

CrossCheck has added over 100 members since December 2012 and now has over 500 publishers using the service. We have seen a corresponding growth in usage, with almost 95,000 documents checked in March 2013. The database itself continues to grow and now contains content from over 37.7 million DOIs from CrossCheck members including PeerJ and the American Chemical Society. Within the iThenticate system, users have had access to the beta-launch of Document Viewer in December. Document Viewer went live in May 2013. One of the new features enables users to print and download from the DV. Users will also see an increase in the size of files they can download (doubling from 20MB to 40MB) and a new addition to how the system excludes matching text under a certain size. More updates are planned in 2013 so we’ll keep you posted on those too.

Participants in the CrossCheck User Group at the CSE meeting in May saw a preview of these features from Mark Ricksen, iThenticate Product Manager. Thanks to all those who attended both this meeting and the CrossCheck session at the COPE European Seminar in March. It was great to meet users and get feedback on the system and how we can support it. Apologies for all the early-morning starts! We plan to hold another User Group on November 12 at the Annual Meeting.

Introductory webinars are still held regularly and potential or existing users are welcome to attend, especially if you would like to find out more about Document Viewer and other new functionality. We’re also planning admin-specific webinars later in the year. If you have any questions about CrossCheck, please email us.


For members participating in both FundRef and CrossMark, funding information will automatically display in the CrossMark record tab. This important information will thus be readily available to researchers and in a way they can find it consistently across a range of publishers and publications.

The last few months have seen more publishers sign-up to CrossMark such as Riga Technical University and the Philosophy Documentation Centre, who are already displaying the CrossMark logo on their PDFs. Elsevier is also scaling-up their rollout of the service to encompass 1250 of their titles. You can see a list of participating publishers on the CrossMark website. Description: http://www.crossref.org/crossmark/images/Logo_index_2.png

CrossMark information can also be queried by CrossRef Affiliates. Microsoft Academic Search implemented CrossMark on their platform in early February. They are now displaying the CrossMark logo on relevant content within their index to show the publisher-maintained version. Inera has also integrated CrossMark within eXtyles so that it now provides a warning if a reference has a CrossMark record that indicates it has been “retracted,” “withdrawn,” or “removed”. This will help publishers keep reference lists up-to-date, and prevent citations of articles that have been corrected or retracted since they were originally referenced. More information for Affiliates about CrossMark is available on the CrossMark website. We will be running webinars to give Affiliates further information on how they can integrate the CrossMark service.

For further information, attend one of our frequent webinars which cover an introduction to the service, how to implement it, and leaves time for questions at the end. You can also email with any questions or visit the website for a gallery of live CrossMark examples and links to up-to-date technical information.

Transfer Code of Practice

On 12 July 2013 the UKSG Transfer Working Group released Version 3.0 of its Code of Practice for public comment. Key updates in Version 3.0 deal with new content types, HTTP redirects, subscriber types, nomenclature, and communication. Public review and comment are invited between now and 6 September 2013.

The Transfer Code of Practice is a set of voluntary guidelines for publishers involved in any journal transfer. It covers thorny issues including ongoing access provision to online content, exchange of subscriber lists, DOI and URL transfer, as well as perpetual access rights to journal content. Learn more.

Tech Corner

CrossRef has released a new Application Programming Interface (API) tool to allow anyone to look up the Registration Agency (RA) for a given DOI or a group of DOIs. CrossRef is not the only organization that doi idf logoassigns DOIs, and each RA provides different services. For example CrossRef's services include reference linking and discovery services for scholarly documents. Until now it has been difficult to associate a particular DOI with the correct RA.

To find the registration agency, simply add "http://doi.crossref.org/doiRA/" before any DOI in your browser address bar or program. These examples illustrate the tool:

  1. Here's a CrossRef DOI: http://doi.crossref.org/doiRA/10.1037/0003-066X.59.1.29
  2. Here's a DataCite DOI: http://doi.crossref.org/doiRA/10.1594/PANGAEA.57055
  3. You can also look up multiple DOIs by separating them with commas. In this case, each of the DOIs was assigned by a different RA: http://doi.crossref.org/doiRA/10.1594/PANGAEA.57055,10.1037/0003-066X.59.1.29,10.5555/test,10.1002/doidoesnotexist

The API is available now to CrossRef members, affiliates, and the general public.

CrossRef Metadata Services Reminder

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.cms logo

IMPORTANT: Please remember that full text or abstracts are not included as they are not part of the metadata and they are not part of the CrossRef deposit.

Publisher members who don't want to share metadata may opt out for each specific organization that signs up for Enhanced CMS. As new CMS applicants apply for the service, CrossRef informs each publisher member (via a Constant Contact email) and provides the opportunity for members to exclude all or part of their metadata for that organization. Members who want to verify whether they've opted out or not, or get a list of all the CMS users, should contact Susan Collins at CrossRef who can send this information.

View a list of our current CMS subscribers.

Recent Enhanced CMS subscribers (since February 2013) with links to opt-out instructions:

Altmetric, LLC
DeepDyve, Inc.
Sciencescape, Inc.

Further information about CMS is available here or read about our CMS policies here.

CrossRef Statistics Dashboard


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 2nd quarter of 2013 were at 475 million and went down by 9% from the same period last year. The number of references submitted that matched a DOI in the CrossRef System increased to 211 million from 181 (in the same period of 2012). Total deposits rose in the 2nd quarter of 2013, with both current and backfile deposits increasing substantially. The number of members and the amount of content in the system continues to grow at a steady rate.
