September 2012

Ed PentzFrom the Executive Director

On September 12th I was very happy to accept the ALPSP Award for Contributions to Scholarly Publishing along with Geoffrey Bilder and Rachael Lammey on behalf of CrossRef (here’s a brief overview of the awards). CrossRef is all about collaboration and our success is due to all the people involved: the staff, the board, members and affiliates - so congratulations to everyone! The next few months are shaping up to be very busy with the Frankfurt Book Fair (see below to set up an appointment with CrossRef staff), the ORCID Outreach Meeting (and launch of the registry!) in Berlin in October and the CrossRef Annual Meeting. The ORCID launch is particularly exciting since CrossRef has been closely involved in ORCID’s founding and start up and is one of the official ORCID Launch Partners. Up through June Geoffrey Bilder was ORCID’s part-time technical director and I serve on the Board of Directors and co-chair the Business Working Group.

In addition to what’s covered in the current newsletter I wanted to highlight two things. The first is that CrossRef is participating in the JISC-funded Open Citations Extension Project run by Dr. David Shotton at the University of Oxford. A number of CrossRef member publishers have agreed to open up references from their journal via CrossRef and the project will demonstrate the value of publishers doing this and also the value of CrossRef acting as a central mechanism for making the data available.  The second is that the CrossRef board had its regular strategic meeting in July to review CrossRef’s development “roadmap” and put text and data mining back on the agenda. Over the next few months we are going to be looking at what role CrossRef might play in this area. At the Annual Meeting I’ll give an update on the full CrossRef Roadmap.

I’m always happy to hear from members so please email me if you have any questions or want to get involved in any of the many initiatives CrossRef is working on.

DOIs in Use: Multiple Resolution in Books

Why do publishers assign CrossRef DOIs to books and book chapters? In a word, discoverability. In a recent post at the Scholarly Kitchen, Kent Anderson speculated on why scholarly book content isn’t cited as frequently as journal content.

One important factor this post didn’t mention is that assigning CrossRef DOIs to book chapters increases the likelihood that they will be found, linked, and cited. Books are the fastest growing content type in CrossRef. People often ask us whether book chapters and reference entries can have individual CrossRef DOIs. Yes, they definitely can! As a matter of fact, more than 5.2 million chapters and reference entries already have CrossRef DOIs. CrossRef supplies metadata, including chapter metadata, to a number of secondary publishers and discovery services, including federated search products and search engines. When chapters are cited, readers are more likely to read them if they are linked with permanent, stable URLs (i.e. CrossRef DOIs). And of course, we encourage book publishers to put outbound reference links in their own book content just as they do in their journal articles.

Many publishers host their books on multiple platforms and wonder how that affects CrossRef DOI assignment. Should the book get two DOIs or just one? The answer is that only one DOI can be assigned to a piece of content. To solve the multiple platform issue CrossRef offers multiple resolution. Multiple Resolution allows a publisher to assign one DOI to the same content located on two different platforms. After clicking on the book or book chapter DOI, the readers will be redirected to a pop-up page where they can choose which platform to view the content on. Below please find an example of a book DOI that uses multiple resolution.

In this example, the Multiple Resolution DOI is assigned to the book title. CrossRef publishers have now assigned DOIs to more than 325,000 book titles.

And Multiple Resolution can also be used with chapters.  Here are examples of DOIs assigned at the chapter level from The Orange Juice Business at SpringerLink below:

Scholarly Publishing Practice 2012

The Association of Learned and Professional Society Publishers (ALPSP) with the help of Simon Inger Consulting is conducting a survey called Scholarly Publishing Practice. The results of this survey will produce a “state of the nation” report for journals publishers. Publishers are requested to fill out this survey and contribute to this very important report. The deadline is quickly approaching so please contribute 25 minutes of your time today. The survey is available at:   

CrossRef Labs: Citation Formatter

crossref labs logoDid you know that CrossRef Labs can help format your citations? Anyone can now retrieve bibliographic metadata in formatted bibliographic entries by submitting a CrossRef DOI.

Many common styles such as BibTex, APA, IEEE, Harvard, Vancouver and Chicago are supported by the citation formatter. Programmers can also use content negotiation to get a CrossRef or DataCite DOI formatted in any CSL style sheet.  

Try it out on the CrossRef Labs site.

Spotlight on Global Publishers

CrossRef has participants from 90 countries all over the world. This summer, staff members had an opportunity to meet with our members and affiliates in Brazil, Serbia, Korea, and China, all of which represent strong and growing parts of our membership.

Executive Director Ed Pentz had a productive trip to Brazil to increase the uptake of CrossRef DOIs in scholarly literature there. CrossRef is in discussions with IBICT (Brazilian Institute for Information in Science and Technology) and ABEC (Brazilian Association of Scientific Editors) about acting as local agents to streamline adminstration and billing for Brazilian members. CrossRef members from Brazil now number 90 publishers.

Another region where CrossRef is rapidly growing is Eastern Europe. Since 2005 doiSerbia has been working to make Serbian scientific research widely available. The National Library of Serbia has joined and will assign CrossRef DOIs to many Serbian scientific journals and make articles available online. The project started with five journals and now has grown to over 64. To learn more please visit or read about their success.

Last spring Ed Pentz participated (via video) in the 5th Belgrade International Open Access Conference 5BOAC. There was a satellite workshop about CrossRef, CrossCheck and the work being done by doiSerbia – a presentation on doiSerbia is available.

Director of Strategic Initiatives Geoffrey Bilder visited with active members of the CrossRef community in Korea this July. He shared CrossRef’s strategic plans, visions and impact with the Korean Council of Science Editors (KCSE), the Korea Institute of Science & Technology Information (KISTI) and the Korean Association of Medical Journal Editors (KAMJE).

CrossRef has 26 members, 27 participating librarians, and 3 affiliates from China. Carol Anne Meyer just returned from a trip to Beijing, where she represented the Society for Scholarly Publishing (SSP) and CrossRef at the 4th Dialogue Between Librarians and International Publishers at the 19th International Beijing International Book Fair. She also had the opportunity to meet with CrossRef member publishers from Tsinghua University Press, Science China Press, Journal of Zheiging University SCIENCE, and with the Institute of Scientific and Technical Information of China (ISTIC), a DOI registration agency. Her hosts included the China National Publications Import and Export (Group) Corporation (CNPIEC) and the Beijing office of CrossRef Affiliate Publishing Technology.

The CrossRef Workshops covering technical, operational and workflow issues will be held on Tuesday, 13 November. The morning sessions will be appropriate for new members and individuals new to CrossRef, and the afternoon sessions will delve into more technical, procedural and operational issues of interest to all members and affiliates. In addition, for the first time, we will hold a CrossCheck user group on Tuesday morning in a concurrent session to the CrossRef Boot Camp (Introduction to CrossRef).

The second day will begin with our Annual Business Meeting. Following that the open meeting will begin with updates on CrossRef activities and guest industry speakers. The day will end with a reception.

Registration is open to all members of the scholarly community, but spaces are limited. See our web page to register and for more information including draft agendas and hotel information.

To get an idea of what the Annual Meeting is like, see these videos from the 2011 annual meeting.


There are now over 300 publishers using the CrossCheck plagiarism screening service powered by iThenticate, and 32.4 million DOIs from CrossCheck members have been indexed in the CrossCheck database that manuscripts are screened against. In the past quarter, there has been significant growth in the number of manuscripts being checked for originality.  In the month of July over 50,000 documents were uploaded to the iThenticate system.  

July saw the first CrossCheck User Group, which was run in conjunction with the 5th International Plagiarism Conference in Gateshead, UK. This meeting provided an update on the status of CrossCheck and offered the opportunity for users to pose questions directly to iParadigms executives. Steve Golik, VP of Product Management presented on the iThenticate roadmap and demonstrated the Document Viewer (DV) functionality, scheduled for later this year which will make the similarity reports produced by the system easier to interpret. Another User Group meeting will be held in conjunction with the CrossRef Annual Meeting workshops on Tuesday morning November 13th.

Introductory webinars are still held regularly and both potential or existing users are welcome to attend. As always, if you have any questions about CrossCheck before applying to join the service, please email us.


Publishers and researchers are becoming more concerned about citing the most up-to-date version of a scholarly document, especially when so many copies are available from so many sources. The CrossMark update identification service launched in April to allow publishers to indicate to users that they are viewing a published instance of a document. Description:

CrossMark now has 8 additional publisher participants. The most recent sign-ups include Cambridge University Press, Mednet and Science Reviews 2000 Ltd. We are currently working with over 20 publishers on their CrossMark implementation and have received over 60,000 CrossMark deposits with more than 350 updates. For more information on CrossMark, you can choose one or all of the options below:

  1. Attend one of our frequent webinars. These sessions last approximately 30 minutes. There is time for questions at the end.
  2. See the CrossMark web site for a short video introduction to CrossMark and information for publishers, libraries, researchers, and affiliates, including a gallery of live examples.
  3. Visit the CrossMark Support site, which is regularly updated to provide useful information on how to implement CrossMark.
  4. Email


FundRef is 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 will allow researchers, publishers, and funding agencies to track the published research that results from specific funding bodies. Plans are underway for a pilot demonstration at the time of the Frankfurt Book Fair in October. The group is also discussing setting up a registry of funders for scholarly publishers to use on an ongoing basis once the FundRef pilot is completed. See the web page for more information and a list of pilot participants.

Tech Corner: Resolving Conflicts

The number of DOIs in conflict has been increasing recently, so we’d like to remind members of our conflict policies.

DOIs are considered to be “in conflict” when they share the same basic metadata (author, title, publication year, page number). Only one DOI should be assigned to a given work. When a publisher acquires a title that already has DOIs deposited, the acquiring publisher must assume ownership of the existing DOIs and maintain them. A DOI conflict penalty fee may be charged if conflicts are not resolved.

Instructions on managing conflicts are available in our help documentation. The Conflict Report lists conflicts by publisher and title – a reminder of existing conflicts is emailed out monthly to the technical contacts of affected publishers.

General Reminder:  Announcements regarding system status, changes, and enhancements are posted in the Announcements forum on our support portal, available here. You may subscribe to this form via RSS feed or email.

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 the 1st and 2nd quarter of 2012 are at a strong 522 million. The matching rate (the percentage of references submitted that matched a DOI in the CrossRef System) significantly increased to 181 million from 91 (same period last year) as did the deposits - both current and backfile. The number of members and the amount of content in the system continues to grow at a steady rate (with the number of book titles increasing 94%) so the CrossRef System is looking very healthy in the 1st two quarters of 2012.

Income Statement/Financial Results
