June 2011

From the Executive Director

A recent Royal Society report (Knowledge, Networks and Nations: Global scientific collaboration in the 21st century) identifies a new group of countries including China, Brazil and India as “emerging as major scientific powers” and highlights Iran, Tunisia and Turkey as countries that are rapidly developing their science base in terms of R&D spending, number of scholarly articles published and an increasing citation impact. The growth in CrossRef membership is following some of these trends. CrossRef membership in Brazil (64 publisher and library members) and Turkey (43 publisher and library members) has grown particularly quickly over the last two years.

In fact, I just returned from a CrossRef seminar in Brazil organized by UFSC – Universidade Federal de Santa Catarina. The seminar brought together over 60 attendees from all over Brazil. I gave overviews of CrossRef, CrossCheck and CrossMark and there were lots of good questions and discussions about improving CrossRef services for smaller, university-based publications using OJS (Open Journal Systems), which are common in Brazil.

Iran is a special case because US government sanctions mean that CrossRef can’t accept Iranian publishers as members although we are in discussions with OFAC – the department of the US Treasury that enforces sanctions – about enabling Iranian journals to join CrossRef – we’ve had requests to join from about 20 organizations.

We expect international membership growth to continue which will increase and strengthen the CrossRef linking network.

In other news please save the date for the CrossRef Workshop Day and Annual Meeting on November 14th and 15th in Cambridge, MA. Also, see below about an important change to the CrossRef DOI Display Guidelines.

CrossRef DOIs in Use: Permanent QR Codes

Quick Read or QR codes, two-dimensional bar codes readable by camera phones and QR reader apps, are everywhere these days. We saw tons of them at the ALA Midwinter meeting in the exhibit hall, and they’ve been popping up at other events. You scan the code with your phone and are directed to a web page for that product or service. Did you know that you can create QR codes for your DOIs too?

The CrossRef Labs page shows how you can generate a QR Code for any given CrossRef DOI.

At the beginning of 2011 the American Institute of Physics (AIP) also launched a DOI QR Code generator called the Permacode Generator on their AIP Labs web site (http://labs.aip.org/permacode-1.209). According to AIP the form has had great use to date.

Either of these tools allows you to submit a DOI and create a QR code to use in publications, on marketing pieces, posters or even T-shirts. Go wild!

CrossMark Pilot Underway

The CrossMark version of record service is in a pilot stage. Four publishers are working to apply CrossMark logos to content from selected publications, in some cases with support from their technology crossmark logovendors. An additional three publishers have agreed to join the pilot in a second phase. We expect that examples from pilot publishers will be visible on their live web sites within the month.

An article in the April issue of Learned Publishing provides background and a complete description of the CrossMark service. See http://dx.doi.org/10.1087/20110202.

To learn more about CrossMark join us for the upcoming Introduction to CrossMark Webinar. The webinar will take place on Thursday June 16, 2011 at 11:00 am EDT. Register here.

DOI Display Guidelines

The CrossRef Board of Directors has approved a change to the CrossRef DOI display guidelines. Effective immediately, CrossRef Member Publishers and Affiliates are encouraged to use the URL form http://dx.doi.org/doi wherever a CrossRef DOI appears online, whether on a landing page, table of contents, blog entry, or in a citation reference list. This action represents a change from the previous recommendation to use the form doi:doi. We will be updating our written guidelines and help documentation over the next few months, but in the meantime, please begin to use the new format as soon as possible.

Presenting the CrossRef DOI as a permanent URL link has a number of benefits. Readers will be able to recognize CrossRef DOIs as standard links, whether or not they know what a DOI is. They will be able to easily copy and paste DOI links into their reference managers and authored papers. Machines will easily be able to crawl and resolve DOIs, and ebooks will be able to easily support the links.

As an example, use the new form

not this

We also suggest that publishers assign CrossRef DOIs that are as short as possible to minimize display
problems (like bad line breaks) in PDFs and printed references.

Linked Data and DOIs

CrossRef and the International DOI Foundation (IDF) have recently announced that all 46 million CrossRef Digital Object Identifiers (DOIs) are now enabled for use in linked data applications.

The term “linked data” describes a set of best practices for exposing data in machine-readable form using the standard HTTP web protocol. These best practices support the development of tools to link and make use of data from multiple web sources without the need to deal with many different proprietary and incompatible application programming interfaces (APIs). Read the news release to learn more.


CrossCheck has recently welcomed its 150th publisher member, the American Physiological Society.

You may view the complete list of CrossCheck members here: http://www.crossref.org/crosscheck_members.html.

The Committee on Publication Ethics (COPE) has awarded a grant to the Journal of Zhejiang University SCIENCE (JZUS) a CrossCheck Member for their project called "CrossCheck Guidance: An Analysis of Typical Cases of Plagiarism in Different Disciplines." Learn more about the project.

If you’d like to learn more about CrossCheck, we‘re running monthly Introduction to CrossCheck webinars. Or for a more detailed technical session on CrossCheck please join us for an iThenticate Demo.

You may sign up for both sessions here

Annual Meeting

It is not to soon to start thinking about CrossRef’s Annual Meeting in Cambridge, MA. This year we will charles hotelrepeat our CrossRef Workshop day on Monday, November 14th, and hold the Annual Business Meeting with important updates about CrossMark and other CrossRef activities, and industry speakers on Tuesday, November 15th. We are planning an interesting lineup, so mark your calendars now.

Cited-by Linking

citedby logoCurrently, members can query our system for Cited-by link matches on a per-DOI basis. We will soon be releasing a new method of retrieving Cited-by links, which will allow Cited-by Linking participants to poll our system daily to retrieve matches at the prefix level. Details will be posted in the “Announcements” forum of our support portal when available.

Billing Reminder

CrossRef's annual fee is invoiced on January 1st, though we send the bills out in mid-December.

Deposit fees are billed quarterly, March 31, June 30, September 30 and December 31.  

With our new accounting system the default is to email the bills, so please update your contact info if
you are not receiving invoices.  If you wish to have them mailed or for updates, please contact Anne, ahotchkiss@crossref.org.

Keeping Information Up-to-date

Turnover, changes in positions and responsibilities all contribute to changes in contact information.  To avoid missing important CrossRef communications, including billing information, please update your contact information regularly by submitting changes to ahotchkiss@crossref.org.
We also haven't surveyed the membership about annual fee revenue categories in a while.
If your annual fee revenue category has changed please submit the new category to ahotchkiss@crossref.org.

CrossRef Statistics

CrossRef’s statistical dashboard shows continued but slowed growth in the first quarter of 2011. Current deposits were on the lower end but still up 3%, total deposits were down 5% from last year. Queries, on the other hand, continued to rise and are up 68% from the same time last year.

Books remain the fastest growing content type. Book deposits are up 26% over last year.
