*Voting members have gone down over the last couple of months because some voting members have become "sponsored publishers" - this means that they participate in CrossRef through a voting member. For example, JST in Japan is a Sponsoring Member for all the Japanese societies that are published on the J-Stage platform so the individual socieites are included in the list of participating publishers but only JST is a voting member.

DOIs in Use

Forward Linking

Uptake of Forward Linking continues to increase. Mary Ann Liebert has gone live with Forward Linking: Journal of Interferon & Cytokine Research, "Review: Role of Blood Platelets in Infection and Inflammation" Sep 2002, Vol. 22, No. 9: 913-922. doi:10.1089/10799900260286623 ( shows a nice set of "cited by" links from CrossRef.

The Royal Society of Chemistry has also implemented Forward Linking. The "Search for citing articles" link (under "Free access") on the following page provides an example of it in action:

For information on CrossRef Forward Linking please go to

Download/Export Citations

We want to encourage publishers to make sure that the "Download" or "Export" citation services on their websites use DOIs as part of the citations and for the link.

If you go to AMS article: Journal of Applied Meteorology: Vol. 44, No. 8, pp. 1161–1179 doi:10.1175/JAM2265.1 ( and click "Create Reference" you can see that the DOI is included as the URL ( which is very good but the DOI is not included in the citation itself. CrossRef recommends that in addition to using the "" link as the URL, that the DOI also be included in the "Electronic Resource Number" field and the citation be given as:

Staebler, Ralf M., Fitzjarrald, David R.
Measuring Canopy Structure and the Kinematics of Subcanopy Flows in Two Forests
Journal of Applied Meteorology 2005 44: 1161-1179

CrossRef has been talking to the creators of reference manager software about DOIs. For EndNote the recommendation is to map the DOI to the "Electronic Resource Number" field in the form doi:10.1175/JAM2265.1 - in future, EndNote will automatically link a DOI in this form. We recommend that publishers also contact the reference manager software companies about creating a specific DOI field.

The AMS guidelines for references provides instructions on using DOIs -

Deeplinked E-Reserves and DOIs

Scott Warren at NCSU Libraries has written an article for the journal Technical Services Quarterly about using DOIs for linking to e-reserves and why DOIs won't be replaced by OpenURLs. He recommends that DOIs should be used for linking to e-reserves and for use in bibliographies and other types of linking.  He highlights a very important point: current style manuals do not call for the DOI to be used in citations. CrossRef will investigate getting this changed. The article is available, with permission or Haworth Press, on the CrossRef website - The published article is available at

Metadata Quality Initiative (or "Increase the Visibility of Your Content")

CrossRef's ability to provide valuable services to its member publishers is dependent on its member publishers depositing good-quality, authoritative metadata with CrossRef. To date CrossRef has been very effective at enabling its core DOI matching and reference linking service but as we move forward with new services it has become increasingly clear that the CrossRef metadata must be improved. The payoff from improved metadata quality for CrossRef members is efficient services the disseminate the metadata for your content, including DOIs, ensuring that your content will be visible in many different locations and services all around the Internet. CrossRef has a number of initiatives underway to improve metadata quality and to improve the data that publishers send to CrossRef.

It is essential that CrossRef members also focus on the issue of metadata quality and use the tools and reports that CrossRef is providing. We ask the business contacts for each member to coordinate with technical staff to ensure that metadata quality is being addressed at the publisher side.

The collective benefits that CrossRef members see through the use of DOIs and the core reference linking service can be expanded to bring even greater benefits, but only if metadata quality is improved. Some key areas for metadata quality are (also see the CrossRef System section below):

Search Engines: CrossRef can provide a service to make it efficient and scalable for search engines to collect metadata and DOIs from CrossRef. However, to be effective this requires additional metadata to be deposited with CrossRef. For instance, as part of the metadata CrossRef could supply is the "crawling URL": Google needs the URL that is sees when it crawls the full text of publisher content so that it can link what it crawls on the publisher site with what it gets from CrossRef.

Use of the CrossRef metadata and DOI will help Google and other search engines link to the publisher copy as the authoritative, published version of the article.

Forward Linking: Many publishers have signed up for Forward Linking and are starting to go live with the links. Because of Forward Linking, metadata submitted by publishers to CrossRef may be displayed on the website of other member publishers using the service. 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.

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.

In future, CrossRef plans to offer publisher-specific reports and recommendations based on the Failed Query Report, but for now publishers must make proactive use of this resource on their own.

Browseable Title List/Coverage Information ( This list has been substantially updated. It is available to browse and search and also to download as a CSV file. This service has been augmented with MARC data and includes coverage information for every title in CrossRef (year, volume, issue, MARC subjects). Publishers should check this data to see if there are any gaps in coverage for their CrossRef-deposited content.

Reference linking: Effective, persistent DOI links are dependent on the URLs associated with DOIs being valid and up-to-date.

Growth in deposits has continued, particularly with books and conferences. The overall rate of growth in the number of DOIs was 42% from 2004 to 2005. Membership grew even factoring in the move of many organizations from voting members to participating publishers (the bulk of this was due to the Japanese societies moving to have JST as their Sponsoring Member).

The one area of decline, which has been consistent this year, is that the matching rate has dropped. Investigations show that the lower matching rate it due to a few large affiliates getting very low matching rates. Many members are closer to 50% in their matching rates and analysis shows that over half of members get a higher than 50% matching rate. Nevertheless, focusing on metadata quality and other issues will help increase the matching rate.

Deposit and query stats are regularly updated at  

Financial Update

3rd quarter financials will be available the week of October 18th. Preliminary figures show that revenue is about 10% above budget with expenses being slightly below budget.

As noted below in the section on the July board meeting, there are no increases to any fees for 2006 and effective July 1, 2005, the book chapter price is lowered from $1 to $0.17.

Administrative/Governance Issues

Summary of Board of Directors Meeting, 26 July 2005

A number of the key action items and decisions from the board meeting were:

1) The Audit Committee and the Executive Committee are to work together to review the Audit Committee policy recommendations, so that they can be submitted to the Board for approval at the November Board meeting.

The Audit Committee will work with the Executive Director as needed to seek bids for a possible change in audit firm in time for the 2006 audit.

2) The Technical Working Group is being asked to look at data quality, working with Chuck Koscher, Bob Hecht and Diana Bittern.

3) 2006 Fees - the board approved the recommendation frorm the Membership and Fees Committee that there be no increase in any of the CrossRef fees for 2006 and that effective July 1, 2005, the price for a book chapter will be lowered from $1 to $0.17.

4) The board appointed a Nominating Committee comprised of Eric Swanson, John Wiley & Sons (Chair), Thomas Connertz, Thieme, Karen Hunter, Elsevier, Bernie Rous, ACM, Paula Duffy, UCP to recommend a slate of candidates for the election.

2005 Board Elections- Annual Meeting and election materials are being sent to members this week. The election will be held at the Annual Meeting in London on November 15th, 2005.  Please remember to return your proxy by for the election. 

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 -

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

Search Engine Update

Google - in September Google held a meeting to discuss publishers delivering metadata to Google Scholar.  A number of publishers at the meeting stated that it would be best to work through CrossRef.  There are a number of proposals that have been sent to the "discuss-search" list about what CrossRef can do to supply metadata to Google (see information below on the "discuss-search" list).

CrossRef is also very close to finalizing a template agreement for CrossRef members to use with Google covering crawling and use of full text content in Google and Google Scholar.

Microsoft - Microsoft has entered into an agreement with a group of publishers represented by CrossRef as part of an academic search service currently in development. The agreement provides Microsoft with the license to crawl and index the full-text journal articles of participating publishers, according to terms and conditions that protect publisher copyright and other interests.

Search Engine Discussion List - CrossRef has created an email list to discuss a range of issues related to academic publishers working with commercial search services. CrossRef may be well positioned to develop a standard interface that could be used by Google as well as other search engines. The advantages to everyone are similar to those in the core CrossRef system: each participant only needs to do the technical interface once and the end user will benefit from a consistent experience across different search services.

The first issue being discussed is whether a "collective" standard would be useful and whether we should use the CrossRef "DOI+CrossRef metadata sitemap" as an element of such a standard interface. Sign up at and join the discussions!

Business Development Update

New Members - JSTOR officially joined CrossRef as a Sponsoring Member in August, and has begun the process of seeking individual publisher consent for assignment of DOIs to the content on its platform. The American Diabetes Association joined CrossRef in early September, for assignment of DOIs to ADA Journals Online. Texas A&M University joined CrossRef in September for assignment of DOIs to the dissertations in its institutional repository.

CrossRef is also very pleased to welcome these new members as of August/September 2005: BC Decker, ACTA Press, Questions Publishing, and the Angle Orthodontist.

The most recent affiliate to join CrossRef is R. R. Bowker, who joined as a Linking Solutions Partner.

Conferences/presentations - In addition to our own annual meeting, CrossRef is gearing up for exhibits at Frankfurt and London Online. Please be sure to stop by and visit -- booth J440 (Hall 4.2) at Frankfurt and booth #212 at London Online. CrossRef staff will be speaking at the Charleston Conference on November 4th, and CrossRef will be present as a sponsor at Internet Librarian 2005.

CrossRef System

Resolution Report Update - the monthly DOI resolution reports were updated this month. The information in the reports now includes a list of top ten DOIs with the most resolutions and it also includes a list of the DOIs that failed to resolve - this will enable publishers to track down problems or see where there is a problem with their processes.

Bad Characters: CrossRef has been scanning the CrossRef Metadata Database for bad characters but we are finding this to be a challenging task since this is a multi-faceted issue. In the short term, CrossRef is identifying the problems and asking the publisher to redeposit the metadata. For the long term, CrossRef is building tools to formulate the error pattern and automatically fix the errors.

Title Management: CrossRef is focusing on journal title information and this will be 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. CrossRef now has sophisticated title management system built into the CrossRef System. This allows CrossRef administrators to establish correct, authoritative journals titles, create "families" of journal titles, and also to add additional ISSNs and alternative journal titles. At the moment it involves CrossRef manually checking journals titles and contacting publishers to fix problems and establish proper titles. The CrossRef mddb.xml ties all this information together.

Lock Titles to prefixes: As of December 1, 2005 CrossRef will "lock" titles to specific prefixes. This will mean that no other member can deposit content for that prefix and will mean that the DOI Ownership Transfer Policies will need to be followed; if a title changes hands, CrossRef can change the prefix the title is associated with.

Direct Deposit to the Handle System: Some CrossRef members deposit DOIs directly to the Handle System and then deposit them with CrossRef. CrossRef needs to limit this since in many cases the metadata and DOIs that are deposited directly in the Handle System are not deposited with CrossRef. In future, unless granted special permission, member publishers will not be able to deposit DOIs directly to the Handle System.

Missing Metadata Report: If metadata such as volume and page number are missing then fewer references will match. Therefore, CrossRef is developing a new report that will show aggregated reports by publisher of which metadata is missing from member deposits. This will help identify metadata that publishers are required to deposit with CrossRef.

DOI News

The September DOI News ( has a number of important items in it. The IDF has developed a patent policy and procedures to ensure the persistence of DOIs through social mechanisms and agreed policies among the Registration Agencies, including policies on the suspension and termination of RAs and what happens to existing DOIs under these circumstances.

The strategic restructuring of the IDF had gotten underway and a plan is in place for IDF to be on a more sound financial footing early in 2006.


The October NISO Newsline is available at  Important items are that the DOI Syntax standard revision has been approved and NISO and ALPSP have set up a working group to examine the problems associated with the proliferation of different versions of journal articles. A number of CrossRef member organizations are participating including ACM, T&F, IOP, OUP and Wiley.

Presentations from the OpenURL and MetaSearch workshops are available (including Chuck Koscher's talk on CrossRef's OpenURL resolver) -
