The reasons why e-journals became the target of choice include history, economics and technical convenience. In this post I will analyze these reasons in the light of what is now almost a decade of experience, and argue that they make less sense than they should.
There are two main answers to the question "why preserve e-journals?":
- Post-cancellation access to subscription material.
- Maintaining the integrity of the record of scholarship.
In this post I'll look at post-cancellation access. I'll return to the problem of maintaining the integrity of the record in a subsequent post.
Many libraries' interest in preserving e-journals arose when it became obvious that a side-effect of the transition of academic publishing to the Web was to change what the libraries were buying with their subscription dollars.
In the paper world the library purchased a physical copy of the content. Their reader's continued access to the content did not depend on continuing subscription payments, only on the library's decision whether or not to de-accession it. In the Web world, the library's subscription leased access to the publisher's copy of the content. Their reader's continued access to the content is perpetually at the mercy of the publisher's pricing policy.
This uncertainty didn't make the librarians happy, and since they write the checks that keep the publishers churning out content, they had various ways to communicate their unhappiness to the publishers. The first, immediate response was to insist on receiving paper copies as well as web access. It rapidly became obvious that this wasn't an acceptable solution to anyone. The libraries' readers rapidly found that they were vastly more productive working with web content. On-line use greatly outpaced use of paper. The publishers soon realized, not just that their readers preferred the Web, but more importantly that it was much cheaper to publish on the Web than on paper. Could librarians be persuaded to accept electronic-only publishing, while maintaining the same subscription pricing?
The major impediment to this tempting prospect was the librarians' insecurity about future access to the content to which they subscribed. Even publisher's promises that they would provide ex-subscribers free access to the content they had paid for weren't convincing; librarians were rightly skeptical of promises whose costs weren't covered.
Two broad approaches to post-cancellation access have been tried. One is to restore the paper model by preserving local copies, in which libraries pay to receive a copy of the content which they can keep and use to satisfy future requests for access. The other is to devise and implement an escrow service, a third party which receives a copy of the content from the publisher and, subject to the agreement of the publisher, to which it can provide ex-subscribers access.
After about a decade of concern about post-cancellation access, we have a small number of partial solutions to the problem. Some are local copy solutions and have been in production use for some years. A few libraries including University of Toronto (.ppt) and Los Alamos use a commercial system from Elsevier (now sold to Ex Libris) called JOS (Journals On Site) to preserve local copies of journals from Elsevier and some other major publishers. About 200 libraries use the LOCKSS system to preserve content from a wide range of publishers, largely disjoint from those in JOS. Others are escrow services, including some copyright deposit schemes at national libraries, and the Portico system. None has yet achieved anything approaching full coverage of the field, all are at a nascent stage. None is routinely providing readers with post-cancellation access.
As time has gone by with no simple, affordable, one size fits all publishers and libraries system for post-cancellation access the world has changed.
First, paper journals are no longer the version of record; for many of the most cited, highest impact journals the version delivered over the network has more information and more highly valued functions. The paper version is incomplete.
Second, the various ways publishers have tried to deliver physical copies of e-journal content, for example on CD-ROM, have proved to be so much trouble to deal with that they have been discredited as a means of post-cancellation access.
Third, the continual increase in subscription costs and the availability of cheap Web publishing platforms is driving a movement for open access to scholarship. It isn't certain that this will continue, and the effect varies greatly from field to field, but to the extent to which the trend continues it again reduces the importance of a solution to post-cancellation access. There is no subscription to cancel.
Fourth, the pressure for open access to the scientific literature has led many subscription journals to adopt a moving wall. Access to the content is restricted to subscribers for a period of time after it is first published, ranging from a few months to five years. After that, access is opened to anyone. The idea is that researchers active in a field will need immediate access to new content, and will justify the subscription to their librarians. Thus librarians will believe that, when their future readers want access, the moving wall will still be in effect to satisfy them. Thus they will be satisfied with a Web-only subscription.
Fifth, some other publishers have decided that charging for their back content on a pay-per-view basis is an important revenue source. These publishers are unlikely to participate in any solution for post-cancellation access.
Sixth, big publishers increasingly treat their content not as separate journals but as a single massive database. Subscription buys access to the whole database. If a library cancels their subscription, they lose access to the whole database. This bundling, or "big deal", leverages a small number of must-have journals to ensure that cancellation of even low-value journals, the vast majority in the bundle, is very unlikely. It is more expensive to subscribe individually to the few high-value journals than to take the "big deal". Thus cancellation of large publisher journals is a low risk, which is the goal of the "big deal" scheme.
Publishers who charge for back content typically do not allow their journals to be preserved using the LOCKSS system. They may provide their content to the nascent schemes for electronic copyright deposit at national libraries, but under very restrictive terms for access. For example, the Koninklijke Bibliotheek and the forthcoming British Library schemes both provide full access only to readers physically at the library itself; others get no or minimal access. National libraries are not a realistic solution to providing post-cancellation access to readers at subscribing libraries. Again, although these publishers may deposit content in the Portico system they're unlikely to sign the:
"rider to the agreement that a participating publisher signs if they choose to name Portico as a mechanism to fill post-cancellation access claims submitted by participating libraries." (emphasis added)
The rider in question is as follows:
"Perpetual Access.[Publisher] agrees that Portico shall provide access to the [content] to [Publisher]'s former purchasers or subscribers. Participating [Libraries] may submit perpetual access claims to Portico by certifying, either electronically or in writing, that they were a purchaser or subscriber to [the content] to which they are seeking access. ... Portico may Deliver the requested [content] if [publisher] has not notified Portico and the [library] of its objection ... in writing within thirty (30) days."
Thus for each library and each publisher, post-cancellation access is subject to the agreement of the publisher after the subscription has been canceled. Despite having a current subscription to Portico after they cancel their subscription to the publisher's content, and despite the publisher's having signed the rider, libraries can't be fully confident of receiving post-cancellation access. For example, suppose that a publisher signs the rider and is then sold to another that regards charging for post-cancellation access as important to its business model. The new owner could simply institute a policy of objecting to all perpetual access claims.
About 1/3 of Portico's publishers currently have not signed the rider. The only access a library obtains to their content is described here:
"The participating Library may designate up to four staff members per campus or system branch that will be provided password protected full access to the Portico archive for verification and testing purposes only." (emphasis added)
It is clear that a scrupulous library cannot look on Portico as a universal, robust solution for post-cancellation access.
There are two fundamental contradictions in the attempt to solve the problem of access to content after a subscription to a service (the publisher) is canceled by subscribing to a service (the preservation system) which prevents access after its subscription is canceled. First, it is not a solution, it is another instance of the same problem. Second, to the extent to which the subscription to the second service is regarded as insurance, it suffers from the same moral hazard as someone who takes out fire insurance then burns down the building himself. Insurance is being purchased against the direct consequences of voluntary actions by the insured. In other areas claims against such policies are treated as insurance fraud.
So we see that no matter how ingenious the proponents of digital preservation for e-journals, there is no realistic prospect of a single solution that provides post-cancellation access for 100% of subscription content the way that paper did. Generally speaking, the smaller publishers will be more likely allow one or more preservation systems to provide post-cancellation access, and the larger for-profit publishers will be less likely. There will always be some level of uncertainty as to whether access will actually be available when it is needed.
The following post looks at the second reason for preserving e-journals, maintaining the integrity of the record of scholarship.
I would like to offer a few words of correction and clarification regarding post-cancellation access and the Portico archive (www.portico.org). David correctly observes that publishers who archive materials with Portico are not required to name Portico as a mechanism for achieving post-cancellation access; it is an option. Many publishers have a variety of means to meet this need; some do not. That it is an option to name Portico as a mechanism to meet this need is communicated clearly on the Portico website and in the rider to Portico's participating publisher agreement (www.portico.org/publishers/publisher_license.html). It is also reflected in the Portico's agreements with participating libraries (www.portico.org/libraries/library_license.html). (More on this below). David correctly observes that to date approximately two thirds of Portico's participating publishers have chosen to execute the rider.
The rider to the Portico publisher agreement which David quotes simply outlines the process whereby a library subscriber status can be confirmed with the publisher prior to providing post-cancellation access via the Portico website. This is a logistical arrangement designed to alert the publisher that access is about to be provided to a library and to give an opportunity for any questions about the library's subscriber status to be resolved. The overall intent of the rider – to enable Portico to act in response to post-cancellation access needs – is clear. Those publishers who prefer to address this need in another way generally decline the rider while pressing ahead with third-party archival arrangements with Portico. .
David's posting may have inadvertently created some misimpressions about how access to the Portico archive is structured. The conditions under which participating libraries may access archived content are detailed in section 2 of the library-Portico agreement and are summarized on the Portico website (www.portico.org/libraries/). For convenience, these conditions are summarized here.
Portico provides all libraries supporting the archive with campus-wide access to archived content when specific trigger events occur, and when titles are no longer available from the publisher or other source. Trigger events include:
A publisher stops operations; or
A publisher ceases to publish a title; or
A publisher no longer offers back issues; or
Upon catastrophic and sustained failure of a publisher's delivery platform.
In addition, select librarians at participating libraries are granted password-controlled access for verification and audit purposes only. This password-controlled access is designed to allow participating libraries sufficient pre-trigger event access to the archive to determine that content is well preserved and that the archive is functioning reliably.
Readers with questions about the Portico archive or how access to it is structured are encouraged to contact Portico directly at firstname.lastname@example.org. I also welcome any questions or comments sent to me directly at email@example.com.
The astute reader will observe two things in the comment above.
First, although the marketing spin contrives to make it look like Portico are disagreeing with me, they have been forced to confirm the factual basis of my statements about their post-cancellation access product. Despite the appearance the comment tries to create, Portico confirms that the post-cancellation access they offer to institutions is subject to three conditions:
1) The publisher must have signed the rider allowing it. A significant proportion of Portico's publishers have not done so.
2) The institution's Portico subscription must be current. There can be no guarantee that it will be, especially if the institution is so strapped for cash that it has to cancel subscriptions.
3) After each cancellation, the publisher must permit Portico to provide access to the content that institution canceled. While Portico may be right that in most cases this would be a formality, there can be no guarantee that it will be.
In other words, if everything goes right, it will work for some publishers, but your mileage may vary. Given this level of uncertainty, it should be hard for Portico to argue that their product is a comprehensive or robust solution to the problem of post-cancellation access.
Second, the trigger events discussed in the latter part of the comment do not apply to post-cancellation access. The discussion would have been more appropriate in a comment on the relevant post, which is where I will address them.
You are mistaken if you find within Portico's response any "marketing spin" or an attempt to create a false impression. Nor has Portico "been forced to confirm" anything. Frankly, I find these conclusions puzzling, and I do not understand why you want to attribute to Portico these negative motivations. I have only attempted to provide an accurate description of the long-term preservation and access role that Portico is able to play.
Certainly Portico does not address – nor have we ever claimed to address - the full spectrum of the community's wide-ranging preservation and access needs for all digital materials. Nor is any single entity ever likely to do so. Publishers and libraries are finding multiple ways to address long-term preservation and access, including Portico. Approximately 85% of the 6,100+ journals in the Portico archive are covered by the post-cancellation rider. In many cases Portico is only one means of addressing this concern. Some libraries and publishers have directly identified and documented mutually satisfactory arrangements; in other cases, publishers and libraries are designating multiple mechanisms to ensure ongoing access. In these early days of managing and preserving access to digital resources clearly the community wisely believes that a "belt and suspenders" approach is in order.
The critical task is to ensure the long-term preservation of and access to important digital scholarly literature. Portico is one – but certainly not the only – mechanism to address this need. The community needs the security that comes from multiple players taking different approaches. Portico's approach, for instance, differs usefully from LOCKSS'. Publishers deliver their original files to Portico, a step which by itself introduces a certain discipline that helps to ensure the integrity of the content and also creates opportunities to directly engage publishers to resolve any data questions. Portico then takes responsibility for actively managing the archived content and ensuring that it will be migrated forward as data formats and technologies evolve. This active preservation ensures that the content will be accessible when trigger events occur. We do not have 100% coverage of journals, nor do we have 100% ability to provide post-cancellation access, but we are constantly increasing our coverage, and we will continue to work cooperatively with libraries and publishers to see to it that Portico successfully delivers on its mission. We have made progress, and we are encouraged by it, but we recognize that preservation is a marathon, and not a sprint.

I updated this topic here.
There's now (at last) a page on the LOCKSS website explaining the post-cancellation access issue.
