February 2013

Ed PentzFrom the Executive Director

CrossRef had a great 2012 and ended the year with 56.4 million DOIs, a 14% increase over 2011, and there were over 530 million resolutions (i.e. clicks) of CrossRef DOIs, a 27% increase over 2011. Continuing the trend of the previous year the fastest growing content type was books. We finished 2012 with 329,000 book titles (an 85% increase from 2011) and over 5 million total book DOIs (CrossRef DOIs are assigned at the chapter level in most cases).
These numbers are important because they show that CrossRef is fulfilling its mission by facilitating persistent identification, linking and discovery of scholarly content. The end results is that the online experience is improved for researchers. CrossRef has many other services and initiatives, and you'll find updates on CrossCheck, CrossMark and FundRef in the newsletter. In addition, the ORCID registry launched in October 2013, and CrossRef has been closely involved with getting ORCID started.      

The folks at CrossRef Labs came up with the CrossRef Metadata Search Beta in 2012. This service enables a very user-friendly search of the CrossRef metadata, and the results can be filtered in many different ways. If you ever look up CrossRef DOIs or metadata you should definitely give it a try.

CrossRef has been facilitating members’ participation in the Open Citations Corpus Project – this is a resource at the University of Oxford that collects bibliographic citations and makes them available as Linked Data. More information about the project and a letter asking scholarly journal publishers to participate is available. CrossRef is facilitating the delivery of data for those publishers who wish to participate - it is entirely optional for publishers to participate.

2013 is shaping up to be another busy year for CrossRef. It's not too early to put the date in your calendar for the CrossRef Workshops and Annual Meeting, November 12-13, 2013 in Cambridge, MA, USA. 

DOIs in Use: CrossRef Supports Article Level Metrics at Nature

Nature Publishing Group (NPG) rolled out implementation of article level metrics last fall. Cited-by data from CrossRef and several other sources allows Nature to display the number of citations to an article. In addition, NPG is using Altmetric to display web links from blogs and social media. DOI web links increase the likelihood that they will be correctly captured.

FundRef Update

The FundRef Pilot, a collaboration between scholarly publishers and funding agencies to provide a standard way of reporting funding sources for published scholarly researfundref workflowch, has been going well and will be finishing soon. A full report with recommendations on next steps will be published in March 2013 and will be followed up by informational webinars. Since the pilot has gone well we expect that FundRef will be launched as a CrossRef service in April 2013 - the CrossRef board will be reviewing the FundRef report at its next meeting March 5-6, 2013 and agreeing on next steps. 

The pilot report and the webinars will include demonstrations of the FundRef workflow in action, which includes a funder name registry, manuscript tracking system integration, CrossRef metadata deposit and the search and display of FundRef data through the CrossRef APIs and the CrossMark service. A diagram of the FundRef workflow is available. See the CrossRef FundRef web page for more information and a list of pilot participants.

ORCID

The ORCID system launched in October 2012 and to date over 50,000 ORCID IDs have been registered by researchers. The CrossRef deposit system has been updated to accept ORCID IDs in CrossRef metadata deposits and we strongly encourage all publishers to consider joining ORCID and integrating ORCID IDs into their editorial, production and online publishing systems. CrossRef will be collaborating with ORCID on some webinars for publishers to review best practices for publisher use of ORCID IDs and integration with the ORCID system. 

CrossCheck

Last year was a busy year for CrossCheck with 88 new publishers signing up to use the service, bringing the total number of CrossCheck participants to 371 by the end of 2012. We are regularly seeing over 50,000 documents being checked per month and 33.7 million DOIs from CrossCheck members have been indexed in the CrossCheck database, making it an increasingly valuable resource.

A CrossCheck User Group was held alongside the CrossRef Annual Meeting in November and gave publishers the chance to ask questions directly to Laurie McArthur from iParadigms, and see a preview of new iThenticate functionality that was subsequently released in December 2012. Several User Group Meetings will be held in 2013, including at the COPE European Seminar in March. Further events will be publicised to CrossRef members when dates are confirmed.

An exciting development within the iThenticate system is the beta-launch of Document Viewer (DV) which represents a clearer way to view the Similarity Reports compared to the text-only reports. The DV allows users to view an uploaded document in its original format, including images, tables and graphs, within the Similarity Report. More information on the DV and how you can start to use it is available from the iThenticate web site.

Introductory webinars
 are still held regularly and potential or existing users are welcome to attend, especially if you would like to see a live demo of the new report display. As always, if you have any questions about CrossCheck before applying to join the service, please email us.

CrossMark

Many leading scholarly publishers are in the process of implementing the CrossMark update identification service on article abstract pages like this one from IUCr: http://dx.doi.org/10.1107/S0907444912045374 and on full-text PDFs. Readers can click on the CrossMark logo and find out if the content is current or whether updates have been made to it such as corrections, retractions or additions. Publishers can also use the CrossMark dialogue box to provide researchers with extra publication information; we are already seeing information on publication dates, the peer-review process, CrossCheck screening and the location of data deposits or registries appearing in the ‘Record’ tab in CrossMark. It is also an ideal place to display FundRef data when this service is launched.Description: http://www.crossref.org/crossmark/images/Logo_index_2.png

Wiley and the American Institute of Physics (AIP) are the latest CrossRef members to start displaying the CrossMark logos on their content, and Elsevier has announced plans to extend their rollout of CrossMark to over 1000 titles.

For further information on CrossMark you can 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.

Add Works to ORCID Using CrossRef Metadata Search

Researchers can now easily add works to their ORCID profiles via CrossRef Metadata Search from CrossRef Labs.crossref labs logo

CrossRef Metadata Search provides a simple search of CrossRef bibliographic data that can help find

  • A particular work, by searching for its DOI.
  • New articles, by searching for query terms.
  • Works by a particular author by searching by name and a part of the title.
  • A work, by searching for its short DOI.
  • Articles within a journal, by searching for an ISSN.
  • A work, by searching for a full citation.

CrossRef Metadata Search is most useful for end-users looking for a quick way to look up works based on query terms, but there are other uses as well.  The service is now "in beta,”, but please keep in mind that it's not production quality just yet. It also has a new domain - search.crossref.org, although the old search.labs.crossref.org will continue to work.

Tech Corner

New title transfer option

When requesting a DOI name ownership transfer, the acquiring publisher must provide CrossRef with confirmation that the disposing publisher is aware of and agrees with the ownership transfer.  For those of you who participate in UKSG's Transfer project CrossRef will now accept any transfers logged in the Transfer notification database as confirmation of a transfer. CrossRef Support will still need to be notified of the transfer by the acquiring publisher, but no additional documentation is required from Transfer participants.

New(ish) APIs

FundRef API: An API for CrossRef's pilot FundRef service is now available to retrieve information using a funder name, funder identifier and/or fund (i.e. grant or award) identifier. Results are returned in UNIXSD format  - documentation is available here. Note that a limited amount of data is available.

Deposit Harvester: The Deposit Harvester allows members to retrieve their metadata and DOIs deposited with CrossRef. The metadata retrieved is in CrossRef’s UNIXREF  format, which delivers the exact metadata submitted in a deposit and includes any citations that have been deposited. Members (or their designated third parties) may only retrieve their own metadata. The service uses the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) to deliver the metadata. Details are available here. There is also a public search interface now available, however we're still tweaking it, so user beware.

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.

CrossRef Statistics Dashboard

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 the entire year 2012 were at a strong 809 million. The number of references submitted that matched a DOI in the CrossRef System significantly increased to 285 million from 140 (in 2011). Total deposits rose slightly in 2012, with current deposits increasing and backfile deposits decreasing slightly. The number of members and the amount of content in the system continues to grow at a steady rate (book titles are still growing fastest at 85% over last year).
