Upcoming Meetings

The 2005 Annual Meeting will be held at IOP’s 76 Portland Place in London ( on November 15th, 2005.  A draft agenda is being put together following last year’s successful format of mixing CrossRef-specific presentations with those looking at wider issues of concern to scholarly publishers.

Technical Workshop - a CrossRef technical workshop was held just prior to the SSP Annual Meeting in May.  The presentation from the meeting is available on request.

DOIs in Use

Forward Linking

Journals on JST’s J-Stage have gone live with Forward Linking.  An example is the following article from the Japanese Journal of Pharmacology:

Maria P. Abbracchio and Geoffrey Burnstock: “Purinergic Signalling: Pathophysiological Roles”. Jpn J Pharmacol Vol. 78 113-145 (1998). 

From the article abstract just click the “JST LinkCenter Cited” logo. Another article is from Plant Production Science:

Hideki Kurosaki and Setsuzo Yumoto: “Effects of Low Temperature and Shading during Flowering on the Yield Components in Soybeans”. Plant Production Science, Vol. 6, pp.17-23 (2003).

In one of the first uses of components, IUCr is assigning DOIs to supplementary material from journal articles. In Acta Cryst (2005). E61, m1251-m1252   [ doi:10.1107/S1600536805016880 ] there is supplemental data including a crystallographic information file (CIF) and structure factor (SF) files - (CIF) and (SF).

There is also more general supplemental data files available in J. Appl. Cryst. (2005). 38, 512-519 [doi:10.1107/S0021889805009234] has a PDF and AVI movie file available:


OUP continues to add titles to the Oxford Scholarship Online project and register DOIs at the book title and chapter level:

St John Damascene . Andrew Louth. Oxford University Press. Oxford Scholarship Online. Oxford University Press. 2002.


 IEEE has registered a large backfile of conference proceedings.  An example is:

Molybdenum gate MOS LSI for FM/AM digital frequency synthesizer receiver. Ohgishi, T.; Akiyama, T.; Enomoto, N.; Solid-State Circuits Conference. Digest of Technical Papers. 1978 IEEE International, Volume XXI, Feb 1978 Page(s):198 – 199.

Growth in deposits and membership continued to be very strong.  In particular overall deposits are up 53% from 2004 to 2005 and the number of members is up 42%.  DOI Resolutions (the number of times DOI are clicked) saw a 66% increase from 2004 to 2005. This is particularly important because it represents actual use of DOIs and traffic to members' sites.

The one area where there have been decreases from 2004 to 2005 are in both the number of queries submitted and the overall matching rate of references submitted and DOIs returned. The fall in the number of queries submitted is related to two things – some members have started to use Stored Queries and have stopped re-submitting references and many of the large A&I databases and publishers have done the initial matching of their existing records and are submitting fewer queries.  Adding DOIs for new content continues but there are fewer queries overall. 

The decline in the matching rate is also due to the fact that many large members and A&I databases are not yet using Stored Queries and are re-submitting previously unmatched references.  In addition, a few large organizations submitting large numbers of queries with a low matching rate drives down the overall matching rate.  In looking at overall matching rates, the median matching rate is 40% and there are 298 query accounts with a matching rate of 50% or higher so the lower matching rate doesn't indicate and underlying problems but it is something we will continue to keep a close eye on.

Cash Balance







On a year-to-date basis (covering the first 6 months of 2005), revenues and operating expenses were both favorable against the budget, which resulted in a $184,000 favorable net income budget variance.  Most of this gain stemmed from a very favorable 1st quarter. The 2nd quarter revenue and expenses were just about on budget and the operating income was $11,000.

The cash balance at June 30, 2005 was $1,730,000.  This cash balance was significantly over the cash budget of $1,305,000 by $425,000.  Increased operating income provided a $271,000 benefit to the variance and under spending in capital expenditures another $134,000.

Most of the significant indicators in the financial outlook (reflected in the 2005 full year forecast) remain very close to budget.  Revenues are forecasted to be over-budget by $92,000, which will partially offset a slight over-budget operating expense variance of $60,000.  The cash balance at December 31, 2005 was forecasted at $920,000 (after disbursements of $200,000 to retire member loan principal, $100,000 of interest payment on member loans, and $125,000 for state and federal income tax payments). 

Administrative/Governance Issues

New staff - Anna Tolwinska joined CrossRef as Administrative and Marketing Assistant. She will be answering the main CrossRef phone and helping Amy Brand and Lisa Hart with a range of activities in the CrossRef office.

2nd Quarter invoices - invoices for the 2nd quarter were sent at the beginning of July. The breakdown of deposits by publisher and title is available at New wire transfer details took effect in June and the new information has been emailed to the appropriate billing contacts.

Forward Linking - those publishers who are now depositing references for Forward Linking need to sign up for the service - information and a link to the sign up form are at

Non-Linking Fee - members who do not implement outbound reference links within 18 months of becoming a CrossRef member are subject to the Non-Linking Fee -

Upcoming Board of Directors Meeting, 26 July 2005

Some key items on the agenda for the board meeting are: the approval of the 2004 audited financials – once approved the audited financials will be available to all members on the CrossRef website, the regular quarterly operations review, a recommendation from the Membership and Fees Committee on fees for 2006 and updates on key CrossRef projects - the Multiple Resolution Pilot, PatientINFORM, Extended Content Types and Free Text Queries. The board will also be discussing the CrossRef Search Pilot (see below) and patent issues (CrossRef has retained patent counsel to do some analysis on patent issues for the organization).

A summary of actions from the board meeting will be sent to Members in early August.

2005 Board Elections- thank you to those members who indicated an interest in standing for election for a board seat.  CrossRef will be in touch with all the details about standing for a board seat in August after the board meeting.  The election will be held at the Annual Meeting in London on November 15th, 2005. 

Committees - A list of the committees and the members of the committees is available at

CrossRef Search Pilot

43 publishers are participating in the CrossRef Search Pilot - information is available at CrossRef Search receives a steady number of queries averaging about 7,000 per day. Discussions with Google are continuing on a number of fronts.  Good progress has been made in creating a standard template agreement for publishers being crawled by Google.  In addition, Google has been testing the “Bulk DOI Sitemap” from CrossRef – this is a file containing the DOIs and metadata from the 43 CrossRef Search publishers.  Using this data will help Google Scholar add DOIs and link to publishers’ sites and will help verify metadata. If the file works well CrossRef will consider expanding this to include DOIs and metadata from all CrossRef members.

The CrossRef Search Committee is still evaluating whether to switch the CrossRef Search results over to come from Google Scholar rather than the regular Google index.  The Committee is still looking at coverage of content in Google Scholar and how update-to-date the Google Scholar index is.


PatientINFORM (pI) went live on July 6th -  The initiative continues to expand with other publishers coming on board. Current participants include Wiley, HighWire publishers, Elsevier, Blackwell, Nature, Springer, T&F Informa and more.  CrossRef hosts the pI website and created the pI registry to enable DOIs to be used for the linking between Voluntary Health Organisations (VHOs) and publishers.  Technical information is available at

The basic model relies on an article registration process where the VHO (e.g American Heart Association) registers a summary item on their site that refers to the full text of a journal article. The registration process, using a CrossRef DOI, notifies the publisher of this link and the publisher then takes steps to make the article freely available to readers coming from that VHO location via a DOI link.

Business Development Update

New Members - Since July of 2004, CrossRef has added 116 new publishers as members. Among some of the recent members to join are the American Association for Cancer Research, Scientific Journal Publishers Ltd, the Japanese Society of Echocardiography, Future Medicine Ltd, and The University of Bath-UKOLN. Among our newer affiliates are the University of Illinois Academy of Entrepreneurial Leadership and ASRC Aerospace Corporation.

For a regularly updated listing of new members, go to

Conferences/presentations - CrossRef was in high visibility at industry events in recent weeks, with presentations at CSE and NASIG, sponsorships at SSP and SLA, and a table at AAUP. CrossRef staff will be speaking at an upcoming AAP PSP publishing seminar in New York on August 18 and at the Fall NISO Workshop on OpenURL and Metasearch -- please see for details on this event.  Please see for a listing of CrossRef past and future exhibits and presentations.

Use of Failed Query Report - All members should make a point of checking the Failed Query Report at (cr_member, ref-linking) on a monthly basis. This report provides information about whether attempts to link to specific publications have failed and why; for instance, you may discover that there have been attempts to link to volumes and issues of your journals that may not yet be registered with CrossRef. CrossRef staff also uses this report to identify publishers and content for recruitment purposes. Be sure to scroll down for links to detailed reports.

Backfile Deposits - The accuracy of CrossRef's revenue projections depends in part on advance knowledge of major back-file deposits. If your company is planning to digitize and register large quantities of back-files in 2005 or 2006, please let us know (

CrossRef System

General System - query performance continues to perform well at the evel of around 1 second per HTTP transaction (one query). Deposits are also running well with no severe backlogs developing during the peak hours of the week.  A high number of backfile deposits have been made and current deposits are running at over 100K per month.

Data Quality/Title Management – Because of Forward Linking, metadata submitted by publishers to CrossRef may be displayed on the website of the publisher of the citing article.  Since the metadata is displayed to users, any errors in the metadata as supplied to CrossRef will show up and reflect badly on both the cited and citing publisher. Particular concern relates to journal titles and the use of proper abbreviations, although article title and author names are also prone to errors. CrossRef has now begun an initiative to scan the CrossRef Metadata Database for bad characters but are rapidly finding this to be a challenging task since this is a multi-faceted issue (example: often data is viewed as being 'bad' because a browser does not correctly handle a character, Unicode hex2010 is an example. This is a valid dash character that Internet Explorer does not display. FireFox does display it correctly).  CrossRef will initially focus on journal title information, followed by author names and article titles.  We will be notifying publishers if there are persistent errors in metadata submitted to CrossRef and ask for member cooperation in fixing any problems in a timely manner.

As a first step in the data cleanup CrossRef will use the title management function now deployed on the CrossRef system. This allows CrossRef administrators to establish correct, authoritative journals titles and add additional ISSNs and alternative journal titles.

DOI Ownership Transfer Policies – New DOI Ownership Transfer Policies are available on the website-  Please note that when journals, books or other content changes owners, the existing DOIs need to be transferred to the new publisher (new DOIs should not be assigned!).  When requesting the transfer the new publisher must provide CrossRef documentation that the previous publisher approves the transfer – this can be done via email but needs to be done before CrossRef makes the transfer of ownership.

OpenURL Queries - CrossRef has been running an OpenURL resolver for over a year. This resolver was built to an early version of the 1.0 specification and also services 0.1 version OpenURLs and has not been modified in response to the release of ANSI/NISO Z39.88-2004. CrossRef will upgrade the resolver to be compliant with the latest specification. CrossRef has a alpha version of the new resolver running which currently meets the SAP 1 community profile and the 'journal' referent metadata structure. Plans are to add support for other genres and then release the resolver as a free service to the public. This free service is intended for individual use only and will not require a CrossRef user ID.

 All CrossRef member publishers continue to be OpenURL compliant by through the CrossRef resolver and by assigning DOIs to their articles.

Web Deposit Form - The Web Deposit form now enables the deposit of journal title and article, book title and chapter and conference proceeding title and article DOIs. The page is available at

Free Text Queries - CrossRef now serves a very broad range of publishers, including many members with limited resources and technical expertise. This was one reason that CrossRef created a web-deposit interface as an alternative to XML batch deposits, so that small publishers were given the option to upload metadata and DOIs manually in textual form. (A total of 21 journal issues have been registered via the website deposit form since June 7.) Similarly, some CrossRef members have been slow to begin reference linking due to technical limitations, underscoring the need for a free text query method of retrieving DOIs in order to facilitate compliance with CrossRef reference linking policies among smaller publishers.

CrossRef staff are exploring how to offer members and other users of our system the option to input unstructured references and receive DOIs in return. Several of the vendors that work with CrossRef offer this capability to their client publishers. We are still trying to assess how valuable this service would be so please contact Amy Brand ( if you would find this service useful!

DOI News

The June 2005 DOI News is available at The IDF Annual Meeting in Bologna went very well  - a summary of the meeting and the presentations are available at

At its June meeting the IDF board approved the IDF Patent Policy and Core DOI Specification.  The Core DOI Specification, which is also at the heart of the ISO TC46 SC9 specification for the DOI standard, represents the current state of the DOI System and completion of first phase of developments. The Patent Policy aims for a balance between an open, core system (the system developed collectively) and value added services created by RAs.

 As background the general goals of the IDF are:

  • DOI to be an open standard and system available to all who want to use it on equal terms
  • Preserve and protect the collective investment in the DOI system and standard
  • RAs encouraged to develop added-value services and features on top of Core DOI System
  • IDF Patent Policy goes along with NISO Syntax standard and ISO TC46SC9 system standardization in establishing IDF as an open standard and system

 Some specific goals of IDF Patent Policy are:

  • To form a generic policy for IDF and all RAs
  • To establish trust among RAs on patent issues
  • Provide RAs and users of DOIs certainty that they won’t be infringing any patents when operating within the Core DOI System
  • Enable and encourage RAs to add value on top of the Core
  • Simple, practical and easy to implement

As a result of its strategic review the IDF is also looking at restructuring its operations and reducing costs.  A plan is being developed for the October board meeting.
