It’s been a very busy few months for CrossRef. We launched CrossMark, a major new service, FundRef, a major new pilot project and pdf-extract/Extracto, open source software/service that extracts references from journal article PDFs. We have also seen strong growth in the number of members, the amount of content (especially books) and the CrossRef Cited-by Linking and CrossCheck services. Details on all these developments are below.
On the subject of CrossMark I would encourage all CrossRef members to give serious consideration to participating in this new optional service. I believe it will have a major impact on scholarly communications and will be very useful to researchers. In addition, it will highlight the critical role that publishers play in certifying and maintaining content and issuing corrections, retractions and enhancements. At present there is no consistency in how publishers notify readers of corrections, retractions and enhancements and, in the case of PDFs downloaded to local hard drives, readers have no way of knowing if the article has been updated. CrossMark addresses these issues through an innovative service.
CrossRef has a great team so I want to thank all the staff for their contributions. In particular, congratulations to Patricia Feeney, Product Support Manager, for 5 years of service and to Chuck Koscher, Director of Technology, for 10 years of service. In addition, welcome to Amy Bosworth, our new Accounts Receivable Assistant and Rachael Lammey, Product Manager (maternity cover for Kirsty Meddings) and Jo Steele, Office Administrator (maternity cover for Siama Begum).
The CrossMark update identification system is now open for participation from all CrossRef members in good standing. Participating publishers mark their content with a CrossMark logo to indicate that they have made a commitment to actively maintain it. Clicking on the logo alerts researchers of any important changes that would change the interpretation or crediting of the work, typically corrections, errata, change of authorship, editions, or retractions.
Publishers may also include optional publication record information (non-bibliographic metadata) like funding sources, peer review, rights, publication history, or location or related data or articles. Six CrossRef member publishers have been piloting the CrossMark service for the past year. Currently over 20,000 documents from 21 journals are displaying live CrossMark logos. Of these, approximately 300 are indicating some form of change or correction. See the CrossMark website for more information and to sign up.
Below please find two examples of articles with CrossMark logos. Clicking on the CrossMark logo shows whether the article is current or has updates. The first example is from the Journal of Legal Analysis from Oxford University Press. The status of this article is current.
The second example is from an IUCR journal called Acta Crystallographica Section D - Biological Crystallography. This examples shows that there are updates available for this article.
(Note: you can open the status box if follow the DOI to the article page and then click on the CrossMark logo displayed on the article landing page.)
CrossRef Labs: Extracting References from PDFs
CrossRef Labs has released an open source tool to extract and tag references from PDF instances of scholarly documents. Pdf-extract is available for download from CrossRef Labs, and a web-based interface called Extracto is also available.
These tools are a first step in helping our members, especially those who publish in PDF only, to more easily comply with CrossRef’s outbound reference linking requirement for journal content. They are still under development, and the labs team welcomes feedback and suggestions.
With 5 million CrossRef DOIs and counting, books remain the fastest growing content type at CrossRef. This number includes more than 290,000 book titles, and many reference entries and chapters.
The CrossRef Books Interest Group is working on revising the Best Practices document for assigning CrossRef DOIs for books. If you have any suggestions, or if you want to get involved, please contact Carol Anne Meyer.
Jason Scott, coordinator of the Archive Team, which is dedicated to saving digital heritage, will speak about preserving digital ephemera at CrossRef’s Annual meeting on Wednesday, 14 November.
This year’s event will take place at The Royal Society in London, UK. The CrossRef Workshops covering technical, operational and workflow issues will be held on Tuesday, 13 November. The second day will begin with our Annual Business Meeting followed by enlightening industry presentations and will end with a reception. We hope to see you there, so please save the date!
CrossRef Cited-by Linking
With the addition of 200 million Elsevier references CrossRef Cited-by Linking is growing rapidly. There are 17.7 million articles with references deposited and over 296 million cited-by links in CrossRef. Here’s an example article that has been cited 227 times – http://dx.doi.org/10.1039/A904518J - click on the “cited by” tab next to the “abstract” tab.
Please consider joining the CrossCheck user session, which will be held in July at the iParadigms user conference in Gateshead, UK on the morning of 17 July. Please register in advance.
To learn more please join us for an upcoming CrossCheck webinar listed on our web site. Or, to find out more about CrossCheck before applying, please email firstname.lastname@example.org and we will be happy to answer any questions you may have. You may also find the Frequently Asked Questions on the web site useful.
On May 2nd CrossRef announced FundRef, a pilot collaboration between scholarly publishers and funding agencies that will standardize the names of research funders and add grant numbers attributed in journal articles or other scholarly documents. The collaboration would allow researchers, publishers, and funding agencies to track the published research that results from specific funding bodies. For more information, see the news release.
