Message from the Executive Director

Welcome to the September Member Update. In between updates, which I try to do every other month, you can keep up-to-date with the latest CrossRef news and information on the CrossRef Blog -

The Frankfurt Book Fair is fast approaching.  I'll be attending and CrossRef has a small stand in the Digital Marketplace - 4.2 J453 - please email me if you'd like to set up a meeting.

We are extremely pleased that Tim Berners-Lee, creator of the World Wide Web and key promoter of the Semantic Web, will be the keynote speaker at the Annual Meeting on November 1st in Cambridge, MA (see below for more details). There are many other excellent speakers and we will be discussing the future of CrossRef, so make sure you register right away - CrossRef is at an important point in its development - we are an established, financially stable organization that is fulfilling its initial mission but there is much more that we can do. The title of the Annual Meeting is "Building on Success" because the board is looking at a number of strategic projects and services that CrossRef could undertake to benefit the industry and improve scholarly communications. In addition to the many excellent external speakers there will be a member panel looking at new CrossRef services so we hope many members attend and participate.

In an important development the Membership Qualifications and Rules have been updated - - to address the issue of Duplicative Works (content such as pre-prints found in Institutional Repositories). Points 12 and 13 in the Membership Qualifications and Rules are new and link into the CrossRef Glossary (

CrossRef will be setting up a couple of working groups to address two important issues. Firstly, CrossRef needs to update its DOI Guidelines ( and we are looking for volunteers to help with this (please email me if you are interested). Secondly, we will be looking at the important area of standardizing metadata in publisher RSS feeds - more information will be posted to the TWG email list about this.

CrossRef Web Services has been moving ahead very well. Microsoft and Scirus have both signed up as CrossRef Search Partners to receive metadata for those publishers who don't opt out and CrossRef has been in touch with other search engines about becoming Search Partners.

CrossRef welcomed a new staff member recently. Julie Hawks joined us as the Metadata Quality Coordinator to undertake a wide range of tasks to improve metadata quality and to work closely with members on improving data quality - so you may be hearing from her.

As always please feel free to contact me with any issues/concerns/problems at

Upcoming Meetings

Frankfurt Book Fair

CrossRef has a small stand at the Frankfurt Book Fair - 4.2 J453 - and Ed Pentz will be attending.  Please email if you would like to set up an appointment.

2006 Annual Meeting, Wednesday, 1 November 2006, Charles Hotel, Cambridge, MA, USA

The agenda for the annual meeting has been finalized and registration is now open - We are very happy that the keynote speaker will be Tim Berners-Lee, creator of the World Wide Web and leading proponent of the Semantic Web. In addition to this there are many other interesting speakers and the theme of the day is "Building on Success". The day will finish with a panel of members and board members discussing new services that CrossRef could develop to help the industry deal with the rapidly changing web environment and improve scholarly communications. As always, there is no charge to members to attend this meeting, the luncheon, or the reception, but pre-registration is required.

Technical Meeting, Thursday, 2 November 2006, Charles Hotel, Cambridge, MA, USA

This year the Technical Meeting will be on Thursday, November 02, 2006 from 09:00-12:00, also at the Charles Hotel. The agenda and registration form for the Technical Seminar following the Annual Meeting are now available -

DOIs in Use

Authors and Bad DOI Links - When DOIs fail to resolve because they do not exist, end users are able to report these errors which end as emails sent to CrossRef support. Often the reason for this happening is that the publisher releases the DOI before it has been actually registered (deposited with CrossRef). One common event is author alerts where the publisher informs the author that their article is being published and they give the author a DOI link to the article. Authors, being very interested parties, immediately go to look at the article and when an error occurs they are very motivated to report the error. This sequence of author notices preceding DOI registration causes a bit of angst and support activity that could easily be avoided.

The message here is to pay careful attention to the timing of DOI registration and the various ways DOIs are made public. Further discussions about this on the TWG would be useful.

BioOne's Forward Linking - went live recently -

APS Forward Linking on PROLA - APS announced that the Physics Review Online Archive (PROLA) has gone live with CrossRef Forward Links. A very good example of Forward Links is the famous article published by Einstein, Podolsky and Rosen in Physical Review in 1935.

Phys. Rev. 47, 777–780 (1935) Issue 10. doi:10.1103/PhysRev.47.777 URL: [A subscription is needed to access the citing articles]

Within the APS PROLA system there are 735 citing articles.  An additional 550 citing articles were found via CrossRef.  These citing articles come from, amongst others, the Journal of Alternative and Complementary Medicine, The Professional Geographer and Philosophical Studies.  This shows that cross-disciplinary, cross-publisher citation indexing can be very valuable.

Oldest Content in CrossRef - With the addition of JSTOR content it appears that the oldest article in CrossRef is:

Transactions of the American Philosophical Society, Vol. 1, Jan. 1, 1769 - Jan. 1, 1771, pp. 293-300. doi:10.2307/1005040 URL:

If anyone knows of any older content in CrossRef please let us know!

CrossRef Web Services and Search Partner Program

We launched CrossRef Web Services ( in June of this year and Microsoft became our first official CWS search partner shortly thereafter, with 98% of CrossRef members participating. A CWS search partner opt out process is now underway for Scirus. Please be aware that the Scirus opt-out process will conclude on September 29th. Any member who failed to receive the relevant communications regarding Scirus CWS should contact Amy at

**For a few months in 2005 the number of conference proceedings titles was calculated incorrectly so the numbers aren't comparable.

The CrossRef statistics show very positive trends across the board. The number of Current deposits has been strong and the number of backfile deposits was very high due to the JSTOR deposits (which finished in August). In particular it's important to note that the overall matching rate of 31% (the number of references sent to CrossRef that find a matching DOI) is well up on last year and the growth of book deposits has increased dramatically.

Most importantly the number of DOI Resolutions (i.e. traffic to member publishers' sites) is up 38% from the previous year.

Important Member Information (Policies, Fees, Financial)

Summary Items from July Board Meeting - the board approved the 2005 audited financials (these will be included in the CrossRef Annual Report which will be available in October). The Membership Qualifications and Rules were revised (see below) and the fee for components was reduced (see below). In addition, CrossRef is getting bids from accounting firms for its annual audit work, a disaster recovery plan is being developed, a strategy and financial review are underway and the slate of candidates for the upcoming election were approved.

Revised Membership Qualifications and Rules - the Membership Qualifications and Rules ( have been updated to address the issue of Duplicative Works (content such as pre-prints found in Institutional Repositories). Specifically, points 12 and 13 in the Membership Qualifications and Rules are new and link into the CrossRef Glossary (

New pricing for components and data elements - CrossRef recently lowered its price for registering components (current and backfile) from $0.12 to $0.06 (that's only six cents!). The same six-cent price also applies to data elements and records within databases.

Invoices - invoices for 3rd quarter (July - September) activity will be sent in early October.  Please use this as an opportunity to pay anything else that you may have open - remember that payment terms are net 30. We spend more time than we would like chasing payment of some invoices so prompt payment is very appreciated.  Email Lisa Hart ( with any questions.

Non-Linking Fee - This is a reminder that after 18 months of membership, all CrossRef members should have implemented reference/outbound linking. Please visit the Golive report to see if you are listed as outbound linking. If you are outbound linking and have informed us of doing so, you should have a "yes" listed under the Reference Links Live column. If you are in fact currently adding DOIs to the references in your publications in order to link out, but are not yet marked in the Golive report as doing so, please let us know as soon as possible via an email message to This will allow us to update our records appropriately.

If technical issues are preventing you from implementing outbound linking, please contact us and we will gladly help with the implementation.

Business Development Update

Banner Ads - help promote end user awareness and use of the DOI. CrossRef now makes its trial Simple Text Query service openly available at This means authors can use the tool to add DOIs to their references at the manuscript stage. You can help spread the word by placing the banner ad on your journal homepages and linking from the gif to The ad is available in three sizes.

Content type survey - CrossRef is conducting a member survey of the various content types that publishers are planning to assign DOIs to. This data will help CrossRef tailor future services to the needs of its membership. We invite members to respond to the short survey below linked to here if you haven't already.

2008 UK Research Assessment Exercise (RAE)

CrossRef has been working with the Higher Education Funding Council for England (HEFCE - and the Publishers Licensing Society (PLS - on the 2008 RAE. A summary of this activity has been provided by the PLS:

"The UK Research Assessment Exercise is a peer review project to evaluate the quality of research in UK higher education institutions. This assessment informs the selective distribution of funds by the UK higher education funding bodies and is administered by the Higher Education Funding Council for England (HEFCE) on behalf of the Councils in England, Northern Ireland, Scotland, and Wales

Academics that are active in research are asked to nominate up to four research outputs for this peer review exercise.  The outputs can comprise a very wide range of materials (e.g. architectural models, PowerPoint presentations) but the majority of submissions are journal articles.  Academics are not forced to participate in the RAE, but there are incentives (both financial and of status) for them in doing so.  Academics choose to take part, and decide which works to submit.

Review panel members increasingly want access to materials - particularly journal articles - in electronic form.  They require access to the authoritative final version of an article, and not to a pre-print held for example in an institutional repository.  HEFCE, CrossRef, PLS, and EduServ are therefore working together to facilitate access to journal articles and book chapters published between 2001 and 2007. 

 Universities will send bibliographic information to HEFCE which will populate a secure data collection system with links to full-text via CrossRef DOIs.  [NB:  If publishers do not use CrossRef DOIs or Various technical challenges related to facilitating electronic access have been highlighted.  Collaboration with CrossRef and EduServ (which provides the ATHENSATHENS authentication there is NO requirement for them to begin doing so.  Those who do are asked to keep their DOI information up to date with CrossRef, especially if they have bought or sold titles.  An ATHENS organisational ID will be established for the RAE, and publishers will need to add this into their customer records.  ATHENS has confirmed that it will not invoice publishers for allowing access for the RAE.]

The licensed materials will be accessible only to RAE panel members and to HEFCE staff administering the RAE, the works will be accessible only for the purposes of conducting the RAE, and all text will be deleted from the data collection system at the end of the exercise. PLS has the right to audit the deletion of materials from the data collection system.  The exercise will end in June 2009.

 Book, journal, and magazine submissions which are not accessible in an electronic format will also need to be accessed by RAE panel members.  For this reason HEFCE will also need to authorise universities to photocopy or scan the full-text of submissions for deposit in the RAE repository.  Although university staff (usually librarians) will do the photocopying or scanning, the universities will not be authorised to retain a copy or to store copies in any way, including in institutional repositories.  

 For avoidance of doubt the licence will not permit:

  • use of the works for any purpose other than the RAE
  • storage of electronic files by the universities
  • storage of electronic files by HEFCE or panel members after the RAE is complete

The licence between HEFCE and PLS as negotiated is free of charge despite the fact that it has value for HEFCE in significantly saving administrative costs.  This reflects the fact that photocopied works underpinned previous RAEs at no cost under a “gentleman’s agreement” between HEFCE and publishers, and also the value to the publishing industry in demonstrating that we can work together to provide innovative licensing and access solutions. 

HEFCE will publicly acknowledge publishers' cooperation and the free licence to use in-copyright materials.  These copyrights are of course held by authors, artists, and/or publishers and all parties will be acknowledged.  Logos for relevant publishing organisations will be displayed on the RAE website.

Endorsement for this licence has been requested from the members of the ALPSP, PA, IPA, and STM copyright committees.  To date Blackwells, BMJ, CUP, Elsevier, IOPP, OUP, RSC, Sage, and Wiley have formally expressed their support.
