Message from the Executive Director

I'm very happy to report that CrossRef's Annual Meeting on 1 November 2007 in London was a great success. The presentations from the meeting are available on the website ( The title of the conference was "Trust, authority, and quality in academic publishing today" and there was a fascinating range of speakers who aren't on the normal circuit of publishing conferences. Trust and trustworthiness came up in all the talks in different contexts. The general points I came away with are that scholarly publishers must understand how trust is changing in the online environment and must ensure that scholarly content is connected to the new trust networks that are developing.  Next year's meeting will be 18 November 2008 in Cambridge, MA, USA so save the date!

At the annual meeting the board election also took place (see below for the results).  I would like to congratulate all the board members who have just been elected. All the board members contribute a lot to the organization and are essential to our ongoing success. ALPSP stood as an Independent candidate and we received some critical feedback about the election process. The election was carried out according to the organization's by-laws but the board did discuss the issues that were raised and the Nominating Committee of the board (to be appointed at the next board meeting) will be discussing this and making recommendations on the board about how to make the procedures as clear and effective as possible for next year's election. In the report below there is also information on the very important CrossRef committees - we are looking for volunteers to join a few committees so please get in touch if you can participate.

The CrossRef statistics look excellent. Deposits are strong and book content is growing which means we are rapidly approaching 30 million DOIs. More publishers have joined Forward Linking and October DOI resolutions (the number of clicks on DOI links - i.e. traffic to members' content) were the highest ever in CrossRef history at 17,686,733.

The Backfile Deposit Fee is now $0.12 (down from $0.17) until the end of 2008. This is a 30% decrease and we hope this reduction will encourage even more backfile deposits. There are a couple of other important changes to the 2008 billing which are outlined below - the annual membership fees are increasing and we are offering the option for prepaying deposit fees (i.e. just pay one invoice a year to CrossRef).

The CrossCheck Pilot is moving along well and will be continuing through the end of the year (see below for more details). We aren't adding any new publishers to the pilot but in early 2008 we will have more information on our plans for the service - the board will be deciding at its first meeting in 2008 whether to move from pilot to production. Also, in the Services Update section there is information about optional participation in full text indexing by Scirus, an authorized CrossRef Search Partner.

DOI names in Use

The Royal Society has digitized its journals back to 1665 and is taking advantage of Forward Linking. For a very good example follow this thread:

1) Go to this article - Rubert Boyce "A Contribution to the Study of Descending Degenerations in the Brain and Spinal Cord, and of the Seat of Origin and Paths of Conduction of the Fits in Absinthe Epilepsy" Philosophical Transactions of the Royal Society of London. B (1887-1895), Volume - Volume 186, Issue -1 pp.321-381. 895 doi:10.1098/rstb.1895.0006 [] - access is open through 30 November 2007

2) On the bottom right side see that the article is reference by 7 newer articles through CrossRef Forward Linking. Click the first link to Rijnberk, G. (1931) Das Kleinhirn. Ergebnisse der Physiologie 31(1)

3) And note that this article is reference by a 1937 article Hare, W. K. (1937) Localization within the cerebellum of reactions to faradic cerebellar stimulation. The Journal of Comparative Neurology 67(1)

This shows the power of following references through time and across publisher systems - very powerful.

Services Update

Simple Text Query - We continue to look for an acceptable solution for controlling inappropriate use of the Simple Text Query service. This service is intended for non-commercial use, low level use. A recent attempt to limit robot access by requiring an image based password has been met with some resistance. We have removed that feature and have returned to daily and monthly limits (based on IP address) which are set sufficiently high so as to only impede large scale automated use of the service. We will also implement access control that removes the limits completely for approved IP addresses.

CrossCheck Pilot - The CrossCheck plagiarism detection pilot launched in earnest on August 1st of this year. Although the process of crawling and indexing participating publishers’ full-text has been a bit slower than anticipated, it is now well underway (with over 2 million articles having been indexed) and publishers are beginning to check documents using a customized iThenticate service that includes the growing CrossCheck database. We expect the pilot to run through the end of the current year.

The eight participating publishers are: the Association for Computing Machinery (, BMJ Publishing Group Ltd. (, Elsevier (, the Institute of Electrical and Electronics Engineers (, IUCr (, The New England Journal of Medicine (, Taylor & Francis (, and Wiley-Blackwell ( In addition to the initial press release, CrossRef staff created a specific CrossCheck information page and white paper, with FAQ addressing editorial issues. CrossCheck has received a good deal of press coverage since launching. Among the notices and articles were a September news piece in Information Today.

The initial pilot is limited and we hope to launch a production service early in 2008 after the board reviews the results of the pilot. A press release with more information has gone out and there is a page on the CrossRef website with more details

CrossRef Search Partner Update - under the CrossRef Search Partner program CrossRef facilitates the indexing of member full text content by authorized CrossRef Search Partners. We do this by providing information from the CrossRef Search Partners. I'm pleased to include the information from Scirus below - of course, it is entirely optional for a CrossRef member to have its full text content indexed.

Communication to CrossRef Publishers about Scirus provided by Scirus

Scirus, Elsevier’s free science-specific search engine, has begun to index CrossRef metadata of scientific publications as part of the Search Partner agreement ( So far, Scirus has indexed Nature Publishing Group, Maney Publishing and The Royal Society.

Scirus is offering all CrossRef publishers the option of having the full text of journal articles indexed (as opposed to metadata only), thereby greatly enhancing the visibility of their journal material, and increasing awareness to a greater scientific community.

Scirus has worked closely with The Royal Society to index the full text of their over 60,000 journal articles. Indexing the full text in addition to the metadata helps The Royal Society to achieve better ranking of its content, increase traffic to its websites and provide a better overall experience for users.

Matthew Llewellin, Production Manager, The Royal Society, says “By indexing the full text with Scirus, we’ll see increased traffic to our site and increased citations of our content, due to its increased accessibility and visibility. We are pleased with our co-operation with Scirus, ensuring our material is indexed optimally and with the highest quality” Naturally, publishers retain control over full text access to their articles. Only users affiliated to institutions with subscriptions to the publisher’s journals will be able to access the full text, as controlled by the publisher’s platform.

If you are interested in participating in this full text indexing program, or require additional information, please visit or contact Saskia van Acker at

Growth in all statistics continues to be very good. Backfile deposits have dropped 7% since last year and this is expected to continue and we could even see much steeper declines in backfile deposits moving into 2008. Total records is up 25% from last year and the number of DOI resolutions is up 23%. One item to note is that the number of books titles is up 65% from last year. It's great to see such strong increases in CrossRef's seventh year.

Financial Update

2008 Billing Changes - please be aware that there are two key billing changes for 2008. The first is that the Annual Membership fees are changing - there are increases in each of the fee categories and a new top tier. This is the first increase in fees in four years. Also, please make sure you are in the correct tier by looking at the 2008 fees ( and by submitting your tier level through the following form: ( The second change is that CrossRef will be offering the option of prepaying deposit fees at the beginning of the year. If a member decides to use the prepay option CrossRef will issue an invoice for 2008 deposit fees based on the previous year's deposits. At the end of 2008 a reconciliation against actual deposits will be made and any difference will be applied to the next invoice.  Adopting this billing method means that you will only have to pay one CrossRef invoice per year - this may save some publishers money on bank wire charges. The board also approved the provision that if a member has 3 or more invoices that go more than 90 days overdue in a year then they will be required to use the prepay payment method. The number of invoices more than 90 days overdue has grown and collections are taking up more staff time so please ensure that your organization pays invoices promptly. We will be providing more information about this but if you are interested in taking advantage of prepaid billing then please contact Lisa Hart - - by mid-December.

Executive Summary:

PILA activities during the 3rd quarter of 2007 covering the months of July, August and September, led to the following financial highlights:
  • $844,000 of revenues were slightly over budget (by $57,000/7.2%)
  • $754,000 of operating expenses---unfavorable to budget (by $24,000/3.3%)---mostly due to high bandwidth charges due to a broken script at an affiliate and higher database maintenance fees associated with the set up of the Denver datacenter. 
  • $411,000 of cash used during the quarter was unfavorable as compared against the budgeted cash used of $216,000.  Of this variance, $226,000 was due to not budgeting for the drop in 3rd quarter accrued liabilities (two large pre-paid items from the previous quarter) that were difficult to properly phase in the budget and will even-out by the end of the year. 

PILA staff prepared the Latest Estimate for the full year 2007, highlighted by:

  • Revenues are expected to be 6.7% ($223,000) over budget due to high Current and Backfile deposits.  Expenses are expected to be 3.8% ($119,000) over budget due to high spending on Contractor fees and Datacenter charges.
  • Operating income including contingency is forecasted to be over budget (forecast of $261,000 vs. budget of $157,000).
  • Cash balances at December 31, 2007 were forecasted at $1,276,000---over budget by $214,000.  However, collection on accounts receivable is becoming a challenge for staff.

A range of committees have been established to carry out important work for CrossRef. The list of current committees and the Chairs is at (username: cr_member password: ref-linking). Members of some of the committees can be from any CrossRef member and not just an organization on the board so we are looking for members who are interested in helping out. The meetings of committees are done by conference call and the meet on varying schedules but usually once a month so it is not too onerous. In particular, it would be very useful to have some new members for the Metadata Quality Committee, the Membership and Fees Committee and the CrossRef Web Services Committee. If you would like more information about the committees or are interested in participating then please contact Ed Pentz ( The Chair of each committee is responsible for the membership of each committee.

System Update

Deposit schema change regarding series publications: Version 4.2.0 of the schema will shortly be available for review. These changes correct a weakness in the schema that allowed ambiguous metadata constructs regarding the relationship of series publications and their constituent volumes. This change will affect book and conference proceeding deposits that are series based. Non series based deposits (e.g. a standalone book) will be backward compatible.

New Initiatives Update

In January 2007 Geoffrey Bilder joined CrossRef as Director of Strategic Initiatives. There are a number of projects that he is overseeing and a short summary of a few of the key things being worked on is below. Further updates will be provided as these projects move forward.

CrossReg (Contributor ID project)

CrossRef is in the project planning phase of "contributor id" service for the scholarly publishing community. This service would provide a mechanism for disambiguating the various people who have contributed to the creation of content that has been assigned a DOI. CrossReg would be based on a social software architecture that exploits user-generated content and which implements a distributed authentication framework.

This architecture recommendation is based on an analysis of traditional attempts to provide name disambiguation and user authentication services. The analysis found that: (a) semi-automated techniques for name disambiguation are still too inaccurate to deploy on a large scale and would require an unacceptable amount of manual intervention; and (b) centralized and federated authentication systems have historically failed when deployed on a large scale across heterogonous Internet resources.

The CrossRef service would benefit publishers by providing:

  • A single sign-on (SSO) mechanism that could be used by publisher manuscript submission/tracking systems.
  • Unique IDs for all CrossReg registrants. This ID would automatically be propagated to publisher manuscript submission/tracking systems that made use of the SSO feature.
  • Access to individual CrossRef registrant publication portfolios.
  • Additional metadata that the user records and chooses to share when they register with the service. This metadata could also be automatically propagated to publisher manuscript submission/tracking systems that made use of the SSO feature.
  • A mechanism for confirming authorship claims. The mechanism would be largely automated and could be easily integrated existing publisher workflows.
  • A service that reinforces the preeminence of the canonical published version of content.

The CrossReg service would benefit authors/contributors by providing:

  • A single sign-on (SSO) mechanism that they could use with any OpenID compliant service, including publisher manuscript submission/tracking systems.
  • A unique ID that could be used as a disambiguation token when working with publishers, granting agencies, etc.
  • A mechanism for building, maintaining and advertising a portfolio of publications
  • A mechanism for recording and sharing other forms of professional metadata (contact information, current affiliation, home page, cv, etc.)
  • A mechanism that will allow publishers to confirm the registrant's authorship claims- a process which will add credibility to their portfolio.

The CrossReg service would benefit CrossRef by providing:

  • A system that will allow publishers to enrich CrossRef metadata with unambiguous author IDs
  • A service that reinforces the preeminence of the CrossRef DOI as an authoritative scholarly reference mechanism

The CrossRef service would benefit other players in the scholarly communications industry (e.g. libraries, grant funding agencies, research evaluation committees, etc.) by providing:

  • Unique IDs for all CrossReg registrants that could be used as a disambiguation token when working with authors.
  • Access to individual CrossRef registrant publication portfolios
  • Access to additional metadata (e.g. contact information, affiliation, etc.) that CrossReg registrants record and choose to share when they register with the service.

Version of Record Record

The CrossRef board has had very preliminary discussions about the idea of reinforcing the researcher’s preference for the official, published version of a document. The system is inspired by the Creative Commons infrastructure and would provide both a logo (for human consumption) and a metadata format (for computer consumption) that would mark the publisher version of content as the Version of Record. This record (the Version of Record Record - VRR) would be created and maintained by the publisher and, as such, would only exist in the publisher's version of the article.   

The goals of the initiative would be to:

  • Provide readers with an instant visual cue to the provenance and presumed trustworthiness of formally published content.    
  • Highlight the value that publishers add to articles.
  • Emphasize that it is the publisher's copy of an article that will contain the up-to-date record of the article's status.


The ticTOCs project ( is a JISC-funded project to develop some tools around locating and using publisher RSS/ATOM feeds. At the moment, librarians and researchers have no single place where they can go and get an organized list of the feeds that publishers are providing. The thinking is that such a list would encourage RSS uptake by researchers and thus (from our point of view) encourage researchers to link to publisher content.

We could easily extend our publisher administration pages to allow our members, if they want, to register pointers to their RSS feeds (ideally, via a meta-pointer to an OPML file). We could then provide a service that allowed ticTOCs (or others) to harvest lists of these pointers. It is important to note that we would not be delivering (e.g. re-syndicating) the RSS feeds themselves- just pointers to the RSS feeds. The RSS feeds would still be hosted and controlled by the publishers.

The other aspect of the ticTOCs project that interests CrossRef is their goal of issuing recommendations on RSS best practices. A brief survey of publisher RSS feeds has highlighted a wide disparity in the quality of the RSS being produced by publishers (e.g non-validating XML, misuse of PRISM elements, etc.) The survey also showed that publishers are, by-and-large, not structuring their feeds so that they can reliably collect statistics on RSS usage. We feel like some guidelines on best practice might help our membership.


CrossRef is considering whether it would be valuable to offer a WebCite® type service ( to archive the content pointed to by URL-based (as opposed to DOI-based) references so that all references and cited web material remain available to readers.

WebCite® is an archiving system for cited webpages and websites which can be used by authors, editors, and publishers of scholarly papers and books, to ensure that cited web-material will remain available in the future. If cited web references in journal articles, books etc. are not archived, future readers may encounter a "404 File Not Found" error when clicking on a cited URL.

A WebCite® reference is an archived webcitation, and rather than linking to the live website (which can and probably will disappear in the future), authors of scholarly works link to the archived WebCite® copy on

Wikipedia Reference Linking

By its own accounting, roughly 10% of the references within Wikipedia entries are broken. Wikipedia also contains a very large number of citations to scholarly literature that do not link out to their sources. As part of an overall effort to increase the use of DOI citations in informal literature, we plan to contract somebody to work on linking existing Wikipedia citations and to develop a tool that would interact with the Wikipedia’s citation template mechanism and ease the creation of fully DOI linked citations.

DOI Citation Plug-in for Bloggers

In so-called “academic blogging,” bloggers often refer to formally published literature. Currently, there are few guidelines and very few tools that make the process of citing formal literature from blogs easy (See Nascent blog post -

The BPR3 ( initiative it working on developing guidelines for the use of citations in blog entries and we will be consulting with them. In the mean time, we believe we could help jumpstart the process if we built a reference platform plug-in that allowed bloggers to easily insert DOI-enabled citations in their postings. We hope to launch the tool at the January, 2008 NC Science Blogging Conference (

The CrossRef plug-in will be built for the WordPress platform, but we are designing the system so that the bulk of the functionality is contained in a shared back-end. We expect that other parties will be able to easily port the plug-in to additional bogging platforms. NPG has already expressed an interest in porting it to MoveableType. The tool will allow a blog author to use a widget-based interface to type in a citation or partial citation and search the CrossRef metadata for it. The results of the search will be displayed in the widget and the author can either click on a hit to follow the DOI to the publisher’s site, or they can click on an icon next to the hit to insert the citation into their blog entry. The inserted citation will be formatted, linked (via the DOI) and will include a COINS metadata record so that bibliographic tools can intelligently copy and paste the citation.
