Our target audience is, of course, made up of researchers, educators, consultants, and practitioners who are using system dynamics.

SDS membership is clearly an attractive package for people working or researching within the field of system dynamics.

The forecast from SWETS for all academic journals across the board in 2001 is about the same as for previous years with a predicted rate of attrition still averaging 5%; with the US slightly higher at 6%. Reasons include: the continuing strength of the US dollar and of sterling, and reduced library budgets.

On the positive side, electronic package deals have gone down well in the industry, especially where there is free electronic access with print subscriptions. There are signs that libraries are prepared to pay for key electronic content and packages. Our Enhanced Access Licence deals, for instance, are doing very well.

In an attempt to stop the attrition and increase the institutional subscriptions Wiley has taken a number of measures to address the above issues:

• Price increases for institutional subscriptions in 2001 have been kept to slightly below previous percentage increase. Free electronic access is available for all institutional subscribers, and, with growing success, for SDS members too.
• Wiley now has a pro-active sales team in place, who are approaching key institutions with bespoke Enhanced Access Licences based around the idea of multi-user and multi-site access. We have already sold more of these in January 2001 than we did for the whole of 2000.

The working relationship between Wiley and the Society’s office has continued to be both productive and efficient, with the ongoing relationship between the various contacts within Wiley and the SDS is, without exception, very good. The system set up between the journals admin department (Sarah Stevens sasteven@wiley.co.uk) and the SDS (Roberta Spencer) for the transfer of information about renewals and new members is working well and there appear to be few, if any, queries.

For some Wiley journals, we are currently experimenting with online editorial office systems that will interface more effectively with other management information systems. We would like to explore opportunities for closer working together between Wiley, the editor, and the Society's office for our mutual benefit, and to reduce duplication of tasks. We are currently actively looking into this.

The Production Editor who is currently responsible for SDR - John McCarty - confirms that publication of issue 16:4 is imminent. Papers are in hand for 17:1. However, there is still a worrying shortage of copy for other forthcoming issues, as was highlighted at the SDS conference.

Our ideal aim is still to have at least one issue in hand at Wiley to provide a cushion and avoid delays if, for any reason there is hold-up with a paper, a copyright permission or the production process.

We have re-assessed our production suppliers during the course of 2000, and are now moving the 2001 volume to a different typesetter, better suited to meeting the challenges of quality and schedule that are required for correct electronic publication.

Some Wiley journals are successfully now experimenting with electronic pre-prints as part of Wiley EarlyView®. The benefits here are that material can be paginated and made available to online subscribers very soon after an author returns their corrected proofs. This could effectively speed up publication and create a paginated and therefore citable article. EarlyView does, however, really require a backlog of papers to justify producing them early.

Some of the ways in which Wiley InterScience, is currently adding value to its journal content (for example pre-print publishing and article-by article publishing), are helped considerably by the receipt of disks. More generally, raising the percentage of disk submissions from authors will bring these important benefits:

• Speed: The early availability of a digital version of the manuscript means copyeditors and typesetters can immediately get to work on the manuscript, and so avoid the delay involved in re-keying.
• Service: Authors will feel reassured, justifiably, that we are making best use of their already considerable effort in creating a digital version of their article, and we will avoid the need to chase them for a disk after acceptance of their manuscript.
• Quality: By using author-supplied disks, typographical errors introduced by re-keying are minimised resulting in a more accurate proof and greater satisfaction for the author, as well as a reduction in proof correction times for the author, the journal Editor and Wiley production staff.

Our objective is to raise the level of manuscript submissions accompanied by an electronic version to 100%. This is an attainable aim and will be coupled with an increased emphasis on this issue through amendments to the instructions for authors in the journal and on Wiley InterScience.

SDR is currently covered by the following abstracting and indexing services:

Computing Reviews, Current Contents/Social and Behavioural Sciences (ISI), Fluidex (Elsevier), Geographical Abstracts: Human Geography (Elsevier), INSPEC, International Abstracts in Operations Research, Psychological Abstracts/PsycINFO, Research Alert (ISI), Social Sciences Citation Index (ISI), Social SciSearch (ISI).

We will continue to look for ways to increase the citation coverage, and any additional suggestions for coverage are welcome.

The SDS has an enhanced web presence at www.albany.edu/cpr/sds/, and

SDR is available online at Wiley InterScience to full subscribers (http://www.interscience.wiley.com/jpages/0883-7066/) Online access includes ALL available archival years of full text (back to 1997 with the abstracts also available for 1996). In addition SDS members, with their 2001 subscription, also receive access to SDR on Wiley InterScience.

• The membership take up of the electronic access to journal is working very smoothly. There are currently 280 members accessing SDR online, up significantly from the figure of 218 reported in February last year. This is very encouraging.
• Sarah Stevens in Wiley's journals administration department reports that she has taken quite a few telephone enquiries from people enquiring about membership and access ("My friend told me to call..."), and that they have gone on to pay by credit card there and then.
• SDS site – Wiley InterScience links will allow guest visitors to view current abstracts and table of contents.

• As mentioned in our previous report, we are keen to see the addition of supplementary material to the SDR homepage, and especially the possibility of making downloadable models available.
• We would need to establish where this material was, who owns it, and how it might best be archived and accessed. (There are some models mentioned – including several based on old SDR papers – at Tom Fiddaman’s site at the following web page: http://home.earthlink.net/~tomfid/models/models.html).
• The aim should be to make full model documentation available as a link from the online System Dynamics Review to wherever the data is finally stored. It will be very important to allow subscribers to replicate models easily, and is an excellent example of how electronic access can offer more than the print version alone. It will also have powerful applications in the teaching of system dynamics theory.

There are some very interesting new internal reports on journal usage via Wiley InterScience now available.

• 1591 online Tables of Contents of SDR looked at
• 378 online abstracts looked at
• 456 online PDFs of the articles looked at
• 135 people were denied access*

(* Basically this means they either had no subscription to the full-text version, or their institution didn't have enough concurrent-user subscriptions.)

Looking more closely at issue 16:1 over the past few months, for instance, we can see exactly what were the most popular papers accessed in this issue during the period from publication up to November 2000.

There is clearly some exciting potential for doing this over a much longer period, with more issues, to assess trends and field development. We intend to report more fully about access statistics in the future.

James M Lyneis's article was the first paper in this issue (after the editorial). We have yet to determine what effect the order of articles in an issue might have on their prospect of being downloaded. (Assuming readers are accessing the material via the Table of Contents rather than by, say, a search across all SDR content available on Wiley InterScience.) On other journals it hadn't always been the first article that has had the most hits.

A huge range of other statistics is available to tell us what access was made of the journal homepage on www.interscience.wiley.com/jpages/0883-7066/:

• Top referring sites include: http://sysdyn.mit.edu/other-links.html and Tom Fiddaman's site (http://home.earthlink.net/~tomfid/sdbookmarks.html)

• Top search engines used to find the journal's homepage on Wiley InterScience (Alta Vista)
• Top search phrases/keywords used to do so (led the most visitors to the site): "system dynamics" and "system dynamics review"
• Which browser most used. Internet Explorer with 61% was well ahead of Netscape with 30%; 86% of these IE hits were using Explorer 5.x
• which platform on user's computer - out of over 800 hits: Windows 98 with 42% vs Windows NT with 22% and Windows 95 with 20%; all others including Linux, Macs, Sun, and Windows 3.1 with 16% combined.

This is the name of Wiley's newly launched collection of online management and business journals.

The aim here is to sell special online access licences - to corporates rather than to academics - by getting them to sign up to packages consisting of subscriptions to several relevant Wiley US and UK journals all at once. There is great potential for upselling SDR to corporates that, say, already take "Strategic Management Journal" or "Leader to Leader".

Wiley has played a leading role in the development of CrossRef, a reference linking service formed by the world's leading scholarly publishers. This unprecedented collaboration allows researchers (with subscriptions) to click on a reference in a journal article and move directly to the content of a cited journal article, typically located on a different server and published by a different publisher.

Such linking will enable readers to gain access to logically related articles with one or two clicks - an objective widely accepted amongst researchers as a natural and necessary part of scientific and scholarly publishing in the digital age.

The CrossRef service uses Digital Object Identifiers (DOIs) to link from the references to the articles cited. DOIs actually work as unique electronic identifiers of where material can be found on the web, unlike URLs which often change. (See the DOI Foundation http://www.doi.org/ for further information.)

However, only very recently created articles will have been given DOIs, and these articles in turn will typically cite other papers that are a year or more older. It will therefore take some time before there is sufficient DOI material online to bring about a worthwhile implementation of CrossRef for all our management and business journals.
