From the Executive Director

There has been a break in the regular schedule of Member Updates since the last one in February 2008 so there is a lot to cover. With this latest Update we are trying out a new HTML format which we hope will be easier to read - feedback and comments are very welcome. Does this new format work for you? What types of information do you find most useful in the Updates? Do you find the Update useful at all?

There have been a number of important CrossRef developments recently. I’m happy to say that CrossCheck launched on June 20th. Working with iParadigms CrossRef has created an effective and efficient tool to aid publishers in verifying the originality of content – i.e. plagiarism detection. We try and make clear, though, that the system itself doesn’t identify plagiarism (since computers can’t, yet, infer human intent) but actually identifies overlapping text from different sources. Twelve publishers are fully signed up and many more are close. We have over 3.5 million articles indexed in the system so far and this is growing quickly. CrossRef is working with iParadigms and editorial systems software vendors on an integration API and we will be developing guidelines and best practices. CrossCheck is something that publishers can really only do on a collaborative basis so please see the full information at and consider joining.

CrossRef Forward Linking has been renamed CrossRef Cited-by Linking to be clearer about what it is. The informational web pages have been updated. If you are not participating in CrossRef Cited-by Linking please consider doing so -- it’s growing into a very useful service for members (see “DOIs in Use” below).

After a long gestation and pilot period CrossRef Multiple Resolution (CRMR) has “gone live” as a production service. CRMR allows multiple URLs to be associated with one DOI and when the DOI is clicked a user is taken to an “interim” page where the different links are displayed. The page can be customized and branded. The most common use of CRMR at the moment is when an article is available on two different platforms as is the case with this DOI – doi:10.3138/C972-1321-8720-314M.

In July the board held its annual two day strategic meeting and I’ll be reporting on that separately. Included below is information on the 2008 elections and updated statistics.

As always, please feel free to contact me with any questions or concerns (

August 2008 Stories

DOIs in Use

The article below is a good example of one of the benefits of CrossRef Cited-by Linking. If you look at this example from Blood - Blood, 15 April 2007, Vol. 109, No. 8, pp. 3360-3368. doi:10.1182/blood-2006-07-033662 – and go to the "Citing Articles via CrossRef" on the right hand side you can see that two of the cites are from the “non-traditional” AfCS-Nature Molecule Pages and a few from “regular” journals, one being a Japanese journal. This demonstrates that while CrossRef Cited-by Linking will take some time to be as comprehensive as other sources it already picks up some very useful information that other sources do not.

2008 Elections

In preparation for the upcoming Board of Director’s election in November at CrossRef’s annual meeting a package of materials, including the formal Notice of Meeting and Proxy Form will be sent on September 30th.  The Nominating Committee, under instructions from the Board to make sure the board is representative of the membership, has proposed the following candidates for election to the Board of Directors:

  • American Institute of Physics
  • American Psychological Association
  • CSIRO Publishing
  • IEEE
  • The Institute for Operations Research and the Management Sciences (INFORMS)
  • University of California Press

Nominations for Directors are done in accordance with Article VII, Section 2 of the By-Laws. I also wanted to remind members about Independent Nominations as described in the By-Laws (Article VII, Section 3). It states:

Independent nominations.  Nominations for Directors may also be made, endorsed with the names of not less than ten (10) members of  the Corporation, if forwarded to the Secretary at least five(5) days prior to the annual meeting of the Corporation for immediate  transmittal by him or her to the members.

We are making the election information available earlier this year so that any members wishing to stand as Independent nominations are aware of the dates to be included in the formal notice of the meeting. This year, the schedule for the Board elections will be as follows:

  • September 24th, 2008: Deadline for Receipt of Independent Nominations to be sent with the formal Notice of Meeting
  • September 30th, 2008:  Date of mailing of formal Notice of Meeting
  • November 13th, 2008: Deadline for Receipt of Independent Nominations
  • November 18th, 2008: Election held at Annual Meeting.

Procedures and Notes. Any Independent Nomination should be sent to Ed Pentz, Secretary at or at CrossRef, 40 Salem St, Lynnfield, MA 01940, USA.

The above table provides a summary of the statistics in the Dashboard with comparisons against the same period last year along with pro-rated budget numbers to give a snapshot of how CrossRef is doing.

The number of queries has increased significantly this year, and the matching rate has stayed high (although a little lower than the same period last year) with the result that 58,000,000 DOIs were delivered in response to queries through the end of June 2008. The number of queries increased due to regular high levels of querying by organizations using the system for a long time and some new entrants. In particular, KAIST (Korean Institute of Science and Technology) had over 13 million queries in 2008, as they fill in their local linking system and databases. Next on the querying front was APA and Aries (makers of Editorial Manager), both with about 9.8 million. In all there are over 1,000 accounts (libraries, publishers, A&Is, etc) that have sent over 100 queries so far this year.

Current deposits have grown 7% from 2007 to 2008 and are just under budget by 2%. This is good growth considering the maturity of the CrossRef system. As expected, Backfile deposits dropped by 33% from 2007 to 2008 but were over budget by 6%. Deposits are proceeding according to projections, but it’s clear that Current deposits will need to continue to increase to offset the decline in Backfile deposits.

DOI Resolutions increased 42% from 2007 to over 123 million for the first half of 2008. This shows that DOIs are widely used and driving lots of traffic to publisher content, but more importantly, it reflects that DOIs are extensively embedded in scholarly journals.

Membership growth has continued at a very good rate increasing 29% from 2007 to 2008. Linking prefixes is the one item that should be increasing more quickly. It can be difficult to track when members actually go live with their outgoing reference links, so we will be looking at better reporting of this later in 2008.

The number of books in CrossRef has continued its rapid increase with a 95% increase from 2007 to 2008 in the number of book titles in the system.

Financial Information

The 2nd quarter invoices were sent out in July so please pay promptly if you haven’t already done so. If you pay by wire please include an additional $25 for the wire transfer fee.

Prepay billing: consider pre-paying your 2009 deposit fees so that you only have one CrossRef invoice per year. Using 2008 deposit numbers, CrossRef can invoice you for 2009 deposits on the same invoice as the 2009 annual fee (to be sent out in early December 2008). At the end of the 2009 an adjustment will done using actual deposit numbers and any credit or extra payment will be added to the invoice for the 2010 annual fee.
