Introduction

During the past ten to fifteen years traditional interlibrary loan (ILL) practices have evolved into hybrid services that offer full or partial electronic access to document delivery. Diminished library budgets and higher user expectations forced library management to search for more effective and efficient models of resource sharing, and combined with the technological advancements of the 1990s these factors contributed to the development of the access model or 'just in time' approach to information provision. Library managers cancelled journal subscriptions, invested in full-text online databases and purchased new forms of telecommunication (Smith & Osborne 2000, p87-88). Meanwhile users were becoming familiar with the electronic age and expected instantaneous access to documents from their own personal computers (Smith & Osborne 2000, p87-88). In this environment unmediated document delivery emerged as an alternative method of document delivery. But do users and libraries benefit from unmediated document delivery?

This article addresses the effects of unmediated document delivery; it defines the term and provides the background for changes to ILL operations, including an overview of previous and current document delivery practices. The report examines the role of document delivery stakeholders and the rationale behind the establishment of unmediated services. It provides a brief analysis of selected trialed and current unmediated services and highlights the key issues that arise from the establishment of these services. The issues discussed are quality service delivery, user acceptance and training, financial management, choice of supplier, inter-operability and standards, and copyright and licence compliance. The wider issue of the role of the library as an information provider is addressed within the context of the access versus ownership dilemma. Finally, a brief summary is given of the future role of unmediated document delivery services.

ILL encompasses the request and delivery of loans and documents; however, for the purpose of this report only documents are discussed and the focus is on issues that arise within larger academic institutions.

Definition

Several terms are used in professional literature to describe the online ordering of documents not held in the library's collection and their delivery to the user without library mediation: 'user-initiated document delivery' (Arkin 1998, p119), the 'just-in-time model' (Roberts 2002, p6) and 'end-user document supply' (Chambers 1999, p71). Unmediated document delivery is the term preferred here. The degree of intervention in the process varies from library to library. Some libraries develop the service, train their users and then have minimal involvement in the process. The user is expected to contact the document supplier directly regarding ordering, financial administration and problems with the delivery or quality of her documents. However, this approach is not common and most libraries choose to co-ordinate these responsibilities.

Any library involvement in the unmediated process is often transparent to the user; if the library does not hold the item that the user requires it can be ordered online from either a subject database, the supplier's database or an online request form, and delivered to the user by fax or electronic document delivery. Users are generally given password access, which allows the supplier to record the transaction and directly bill the library or the user's department. Some libraries choose only one document delivery supplier, particularly if their users require material in a specialised subject area, while others offer a selection of suppliers which cover a range of disciplines.

Stakeholders

There are three main stakeholders in the unmediated document delivery process: the users, the suppliers, and library staff and management. In academic libraries the users are mainly students, academic staff and researchers who access library resources internally or externally. These users have different expectations and needs, use the library to varying degrees and have a range of information technology skills, but their common desire is to quickly and easily locate and receive their documents (De Saxe, 2001). A number of commercial document delivery suppliers have entered the market and are seeking to supply end-users with document delivery services and in some instances by-pass library staff; these are publishers, other libraries, journal agents or dedicated document delivery services (Mark 2000, p134). But while suppliers are eager to take up the market, often they do not want to have direct contact with requestors or locate difficult material. Library staff and management have adapted to the shift to the access model and recognise their responsibility to supply users with all their information needs, regardless of whether the library holds the item or the user accesses the collection locally or remotely (Birch 2000, p13).

Rationale

Changes in libraries during the 1990s drew together these stakeholders and initiated the development of unmediated document delivery services. From 1991-1998 ILL transactions increased seventy-one per cent for the member libraries of the Association of Research Libraries (Houle 2000, p118). This increase was a consequence of reduced library budgets, which forced the cancellation of journal subscriptions and also saw the emergence of competitive commercial document delivery services (Smith & Osborne 2000, p87). The traditional ILL process requires the user to check the catalogue and submit a request to the library if the item is not held. The library then manages the entire process; it sources the item from another library or commercial document delivery supplier, processes it on arrival and then delivers it to the user. Unfortunately, the increase in ILL requesting workloads in the 1990s resulted in the decline of the supply service: consequently it became difficult for library staff to provide their users with a consistent turnaround time for requests to other libraries (Sood, 1999). The high total cost of an interlibrary request, an average combined cost of US$29.55, and unpredictable turnaround times saw many libraries select unmediated document delivery through commercial suppliers or co-operative agreements with other libraries as an alternative to their current interlibrary practices (Houle 2000, p118).

Technological developments provided a further impetus for the establishment of unmediated document delivery services. World Wide Web browsers offered a universal interface and the emergence of standard protocols facilitated the searching, requesting and retrieval of documents by lay users. Ariel was developed in 1990 and provided an electronic document delivery software package that managed the scanning, communicating and printing of paper-based documents (Siddiqui 2003, p57). Increased full-text availability and a familiarisation with information technology fuelled users' expectations about the accessibility of documents (De Saxe 2001). Coupled together these developments ushered in the establishment of unmediated services that were often partially subsidised by funds made available from cancelled journal subscriptions.

Examples of unmediated services

Libraries have trialed and established unmediated document delivery services using different approaches and with variable success. A common approach is to use a single supplier which delivers documents direct to the user for items located in their database. Examples of this approach are the CISTI Source/SUMO service at McGill University (Houle 2002) and the EbscoDOC project at Wichita State University (Downes & Naylor 2001).

The CISTI Source/SUMO service was introduced in 1996 at McGill University and allowed staff and graduate students to search the CISTI database, order articles and have them delivered to their desktop (Houle 2002, p217). The service was funded by the cancellation of low-use (as determined by a user survey) journals, and it gives users access to 14 000 journal titles dating back to 1993. Documents are delivered via Ariel or ftp usually within one to two days. The fill rate is ninety-two per cent and between 1 November 1996 and 31 January 2001, CISTI Source supplied a total of 58 708 documents (Houle 2002, p219). The measurement of its success was that the cost of delivering documents from a single title never exceeded the cost of the title's subscription (Houle 2002, p220).

Wichita State University chose EbscoDOC, (which ceased operations in September 1998) as their document delivery supplier during a two-year trial that commenced in 1996. Access was given to staff only, with more than 30 000 titles available and documents delivered by fax, Ariel or mail (Downes & Naylor 2001, p42). The purpose of the trial was to discover the effect of the new service on traditional ILL use (Downes & Naylor 2001, p43). Several patterns emerged from the results of the trial: forty-three per cent of staff used only ILL, thirty-four per cent used ILL and EbscoDOC, ten per cent used EbscoDOC only and thirteen per cent used neither service (Downes & Naylor 2001, p47). At the conclusion of the trial the library decided that the unmediated document delivery service would be discontinued. Results of the trial and a survey of users indicated that changes to the service would be necessary if it were to continue. The service needed to be more user-friendly, have a comprehensive database, provide assistance for users with incomplete citations and improve the quality of its documents (Downes & Naylor 2001, p53).

Other libraries elected to provide users with access to unmediated document delivery through multiple suppliers, using databases that cover a range of disciplines with a choice of document delivery or full-text availability. The University of Leeds Document Direct Service (Birch & Young 2001) and the University of Sydney DIRECT service (De Saxe 2001) are examples of unmediated services that use multiple suppliers.

The University of Leeds began a project service for staff and research students in 1999 for a period of nine months. Six suppliers were selected: British Library Inside Web, Carl UnCover, Technology University of Delft, Royal Society of Chemistry (RSC), AskIEEE and BioMedNet (Birch & Young 2001, p7). The suppliers used a variety of delivery mechanisms and the average cost was £10.30. Users ordered 1467 requests and the British Library's Inside Web service supplied sixty-one per cent of the total requests with a fill rate of ninety-four per cent. The popularity of Inside Web was attributed to its extensive database, fast turnaround, the high quality of the documents and a facility that allowed the user to track their requests (Birch & Young 2001, p7). The project became a twelve-month trial service in March 2000 with Inside Web as its only supplier. The university plans to re-establish the service at a later date with funds from journal cancellations (Birch & Young 2001, p10).

The University of Sydney began its trial in October 1999 for a period of fourteen months, after which the service was incorporated into the library's current document delivery service. The suppliers chosen to provide the service were the British Library's Inside Web, Elsevier's ScienceDirect, Infotrieve, Ingenta (formerly UnCover), and Ovid. Total expenditure was $92 356; a total of $89 452 was used to supply 7260 requests ordered via the Ovid databases, with Infotrieve as the document supplier. Requesting via the Ovid databases was the most popular choice for users, however the lack of promotion of other suppliers (many library staff were not promoting the Inside Web service) could account for the high number of requests via the Ovid databases (De Saxe 2001).

Issues

A number of issues emerged during an analysis of the unmediated services outlined above and of the professional literature relating to unmediated document delivery. The key issues identified were:

• quality service delivery;
• user training and acceptance;
• financial management;
• choice of supplier;
• inter-operability and standards;
• copyright and licence compliance.

Quality service delivery

Quality service delivery provides the user with a consistent and efficient service and determines the success of an unmediated service, as users will become frustrated and no longer use the service if the document supply process becomes problematic. The main aspects of quality service delivery are:

• the quality of documents and delivery methods;
• a rapid response to users' queries;
• the establishment of quality assurance.

The quality of documents and delivery methods is important for users. The delivery of high quality documents is vital for institutions with science and engineering faculties as many include detailed graphs and graphics. Suppliers should provide electronic document delivery using Ariel; earlier unmediated trials with fax delivery experienced problems with the quality of documents (Orr & Dennis 1996, p29; Haslam & Stowers 2000, p86). Ariel software allows for the scanning and transmission of documents, and Prospero software converts the Ariel TIFF files to PDF files, which can then be mounted on the internet for collection. The user is notified by e-mail that their document is ready for collection and the document can remain on the server for a specified time. These documents are of a superior quality to fax, as the print resolution is up to 600 dots per inch (Siddiqui 2003, p58). However, difficulties still exist with electronic document delivery as incorrect scanning may result in missing or unreadable pages or the user may require technological assistance to access the document. In these situations the user needs to have a readily accessible contact person, whether it is library staff or a document delivery supplier.

Therefore, before an unmediated service is established the responsibility for providing a follow-up service needs to be determined because replying to users' no-fill queries and problems with accessing documents contributes to the cost of unmediated services (DeSaxe 2001). And the user will react negatively to the service if not provided with a point of contact, contact details and a timeframe for a response to their queries. Problems accessing electronic documents often arise from local server issues where the library is often better equipped to assist the user than the supplier. Downes & Naylor (2001, p53) determined that users prefer to have one location where their queries can be addressed: if the library has chosen multiple suppliers it may be less confusing for the user if the library responds to all queries.

The establishment of quality assurance measures is necessary to monitor performance. Quality assurance involves the systematic monitoring of the service and the establishment of performance indicators. This process includes gathering statistics and data such as, requestors' details, document details, turnaround time, fill-rate and the source of the document. If this information cannot be provided by the supplier/s the library will need to create a database and develop a process for retrieving and recording this information, an analysis of which will enable the library to develop performance indicators, determine usage, weaknesses in its collection and measure the performance of supplier/s.

User acceptance and training

Generally users have responded positively to unmediated services. They have appreciated the convenience of desktop ordering and delivery of documents and the improved turnaround times offered by unmediated services (Birch & Young 2001, p7; Houle 2001, p220; Orr & Dennis 1996, p28). The tracking facility offered by Inside Web and Web of Science also received the approval of users as they preferred to monitor their requests and not feel they had disappeared into a 'black hole' (Orr & Dennis 1996, p28; Crowley & Hart 2000, p181; Birch & Young 2001, p7).

However, not all users were enthusiastic about unmediated services and some bypassed them in favour of traditional ILL. Several reasons are suggested for this outcome: time constraints, the reluctance to learn a new system, the perceived complexity of the system and the lack of subject coverage of the chosen database/s (Arkin 1998, p121; Downes & Naylor 2001, p53). To overcome user reluctance libraries may need to provide training and to promote the service. The University of Leeds decided to adopt a user-centred approach and during the trial of its unmediated service provided library users with a handbook, intermittent training and awareness sessions, and information about the service via a website (Birch 2000, p14). Library staff should continue to promote the service following initial training sessions and remind users of the advantages of an unmediated service (De Saxe 2001).

Financial Management

The financial management of an unmediated service needs to be resolved before the service is developed as it determines the degree of library mediation, choice of supplier/s and level of funding. Farrelly (2002) in her paper outlines a number of financial management options:

• library funded - no limits;
• library allocation to 'departments' - with limits;
• library funded access to certain titles in lieu of subscription;
• departmental allocation from an acquisitions budget;
• user pays (therefore no user authentication needed).

The level of funding for unmediated services is often linked to the cancellation of journal subscriptions. Some libraries have justified these cancellations with data that compares the cost of cancelled journals to the cost of the unmediated documents requested from those journals. This data has shown the subscription cost to be higher than the cost of the requested documents. (Birch & Young 2001, p6; Haslam & Stowers 2000, p86; Houle 2002, pp219-220).

Unmediated services with multiple suppliers increase the amount of staff time needed to oversee accounts, monitor user authentication and access, analyse reports and statistics, and follow-up financial issues. If the library is only responsible for the co-ordination of access and financial reports, and individual departments are allocated accounts, financial management is less burdensome. The University of Nevada Library (Haslam & Stowers 2000, p83) and McGill University Library (Houle 2000, p120) used this approach with their unmediated services; each department was allocated a separate account and password. This allowed the library to track usage and expenditure, and supply reports and statistics. Libraries which took complete responsibility for financial management and expenditure control found it a time- consuming process that contributed to their staff costs (De Saxe 2001; Arkin 1998, p122; Orr & Dennis 1996, p30).

Choice of supplier

The choice of supplier/s needs careful consideration. Firstly the library should determine the type of unmediated service it wants to provide and then assess each supplier against this criterion. Sellers & Beam (cited in Haslam & Stowers 2000, p82) state that an ideal service would allow:

• direct ordering from a bibliographic database;
• linkage to library holdings with a blocking mechanism;
• ease of use to minimise the need for assistance;
• journal coverage that meets local needs;
• reasonable charges comparable to ILL;
• no use of library staff for processing, that is direct delivery;
• automated reports;
• multiple delivery options.

The use of library staff in processing, automated reports and delivery options have been discussed under quality service delivery. A combination of direct ordering from a bibliographic database, linkage to library holdings with a blocking mechanism and ease of use help to form a seamless unmediated process and also reduce the number of requests for items held by the library. Duplicate requests increase expenditure and were a common problem in libraries that completed trials or established services. A total of twenty-three per cent of requests for the University of Nevada (Haslam & Stowers 2000, p85); fifty-seven per cent for the University of Sydney (De Saxe 2001); and thirty-five per cent for Aalborg University, Denmark (Arkin 1998, p121) were for items already held by these libraries. Although the installation of blocking mechanisms did reduce the number of duplicate requests for the University of Sydney Library (De Saxe 2001) the cost of this added feature, quoted as $10 000 by Haslam & Stowers (2000, p82), needs to be assessed against the cost of library staff monitoring duplicate requests.

Journal coverage must meet the needs of the users; a comprehensive database contributed to the success of Inside Web at the University of Leeds (Birch & Young 2001, p7), while a limited database led to a negative response from users of EbscoDOC at Wichita University (Downes & Naylor 2001, p53).

It is difficult to compare ILL and document supplier charges as they are influenced by a number of factors such as the level of service, the method of delivery, negotiated volume discount and added copyright fees. In Australia the standard or core cost of ILL is set by the Australian Library and Information Association (ALIA) and is currently $13.20 with a turnaround time of five working days (Australian Library and Information Association 2003). Infotrieve currently charge A$14.00 for a standard request, but also charge an added A$8.00 fee for documents that cannot be sourced from their primary suppliers: no turnaround time is indicated (e-mail communication from Infotrieve on 12 February 2003). The British Library's Inside Web service is subscription-based and the cost is dependent on the number of users and the standard fee is approximately £7.20 with 24-hour turnaround (British Library 2003). These brief examples demonstrate the complexity of charging schedules and the need for libraries to assess all factors before they select a supplier based on their charges.

Other considerations when selecting a supplier are turnaround time, fill-rate and the decision to select either a single supplier or multiple suppliers. Suppliers which source documents from their database holdings only generally have a high fill-rate and short turnaround time. An example is CISTI Source with a fill-rate of ninety-two per cent and a turnaround time of between one and two days (Houle 2002, p219). The predictability of turnaround time and fill-rate drops with suppliers which source documents from other suppliers, libraries or publishers. The decision to use a single or multiple document delivery supplier is dependent on the coverage of the supplier/s database and whether it meets the needs of the users. The use of a single supplier can create problems if the supplier ceases operations, as occurred with EbscoDOC (Downes & Naylor 2001, p45), increases charges or reduces the quality of service. Multiple suppliers provide the user with a wider range of journal titles, but increase the complexity of the service, which reduces user acceptance and complicates financial management. De Saxe (2001) noted that the number of suppliers made the financial management of their service time consuming for library staff.

Inter-operability and standards

The key to a seamless unmediated service is inter-operability between systems by the adoption of standards; a combination of Z39.50, the ISO ILL protocol and the Generic Electronic Document Interchange (GEDI) standard are important for the success of unmediated services. The introduction of the Z39.50 (ISO 29350) standard assists users by allowing standardised searching across databases and its use is now widespread. The ISO ILL (ISO 10160/1) protocol allows communication between interlibrary management systems, but it has not been widely adopted (Braid 2000, p9-10). The GEDI (ISO 17933) standard enhances unmediated document delivery and improves turnaround times; it was published in 2001 by the International Organization for Standardization (ISO) (International Organization for Standardization 2003). Inter-operability with financial software would also assist library staff and reduce their workload, but was not a feature of the unmediated services researched in this report. Collaboration between libraries, information providers and system designers is needed to achieve the ideal integrated service (Walker 1998, p48).

Copyright and licences

Orr & Dennis (1996, p28) noted that UnCover charged high copyright fees for some articles, which if ordered from Australian libraries would have been covered by fair dealing and would not have incurred an extra fee. But unmediated services can assist libraries that find the complicated restrictions surrounding electronic journal licences difficult to manage. These restrictions control user access, place embargoes for a variety of periods and limit ILL transactions. (Houle 2000, p118).

The role of the library as an information provider

Do unmediated document delivery services change the role of the library as an information provider? Technological change and higher user expectations have already challenged libraries and altered their traditional role; many now function as hybrid libraries that provide both traditional and virtual services. The shift to the access model will continue as libraries develop more user-oriented services that offer access to information regardless of its location.

The ASHE-ERIC Higher Education Report noted:

The National Center for Education Statistics found that from fall 1995 to academic year 1997-8, the percentage of higher education institutions offering distance education increased from 33 percent to 44 percent. (ASHE-ERIC Higher Education Report 2002, p2)

The increase in distance education programs in part forced libraries to move towards the access model and this is where unmediated services continue to play a major role. Distance education students do not all live remotely however: some are students who choose to study a mixture of on-campus and off-campus courses (Kirk 1999, p43). Unmediated services are important for students studying off-campus as they offer them the same access to information as their on-campus counterparts. Students can connect to electronic databases and order documents not held by the library; unmediated services allow students to connect to library resources twenty-four hours a day, seven days a week from any computer with internet access. The ownership model limits user accessibility to the library's physical collection and budgetary constraints do not allow libraries to offer longer opening hours.

However, technological problems such as slow access caused by limited bandwidth and erratic connections to host computers have been reported by users of electronic resources (Moahi 2002, p344). Also the costs involved in training library staff and users, upgrading hardware and software, and maintaining the technical support infrastructure can be an expensive addition to the library budget (Houle 2000, p118).

Libraries should also consider the consequences of reduced visits to the library by staff and students. Libraries may need to develop innovative solutions to maintain their profile, as less face-to-face interaction will diminish the number of opportunities for library staff to promote services and assist users.

Two meta-issues that face libraries are the increase in journal cancellations following the introduction of unmediated document delivery services, and consortial buying of electronic resources. Journal cancellations may affect traditional interlibrary services if it becomes difficult to supply articles from cancelled journals, particularly those published by small publishers, as often they are not available from electronic databases. Consortial buying of electronic resources has increased and will result in the standardisation of library collections. While collections will be limited, the positive aspect of consortial buying for unmediated document delivery may be the ability to negotiate national or institutional site licences, and thereby allow users access to a wider range of electronic resources (Farrelly 2002).

The future

The future role of unmediated document delivery in libraries is difficult to predict, but changes in the publishing world offer a number of possible scenarios. Authors are publishing more material on the internet either by themselves or co-operatively with their institutions; this material cannot be ordered through unmediated services and a lack of bibliographic control will make it difficult to locate without the skill of trained library staff (Smith & Osborne 2000, p87). While publishers will lose this market to the internet their control over the content of e-journal databases is increasing, and gives them the potential to simultaneously control access to knowledge and connive at restricting access via hard or soft copy subscriptions potentially resulting in library collections that may be weak in certain areas (Roberts 2002, p9). And as more journal titles are published in electronic format only, under license agreements that make them unavailable for ILL, unmediated document delivery may be the only way to access articles from certain journal titles.

Alternatively, partnerships between publishers and libraries may be the way of the future. Morrow (2001) describes a United Kingdom joint project between Ingenta and the University of Lancaster called EASY which aims to test the feasibility of filling document requests direct from publishers' servers. The service is designed to be integrated into existing ILL services; and benefits publishers, by providing them with an income from the supply of articles; users, by supplying ready access to documents; and libraries, as the charge will be the same as normal ILL delivery. Morrow (2001) comments that the British Library Document Supply Centre are also exploring this method of document delivery and are negotiating with publishers about acquiring e-documents which can be delivered through their ILL system.

But the key to the future success of unmediated services will be value-added services that provide a 'one stop shop' or integrated gateway where users can access and satisfy all their information needs. These gateways should provide access to electronic versions of journals; other important publications that are relevant to users; digitised versions of photographs, rare books and fragile material; and searching should be seamless, with easy ordering and reply mechanisms (Smith & Osborne 2000, p88).

The gateway approach to unmediated services is currently being assessed by the Australian Academic and Research Library Network (AARLIN) in a project that seeks to develop:

...a national virtual research library system that will provide unmediated, personalised and seamless end user access to the collections and resources of Australian libraries and document delivery services (including commercial services). (AARLIN 2003)

Integrated gateways will expand the role of unmediated services in libraries and improve user access to a wider range of information.

Conclusion

There is no simple answer to the question - do users and libraries benefit from unmediated document delivery services. The advantages for users are 24-hour access to a wider range of material regardless of location and the convenience of desktop ordering and delivery of documents. But these advantages are only evident to the user if the library develops and maintains the quality of their service. To provide this level of quality and thereby reduce user frustration the library needs to ensure documents are of a high standard, that providers respond quickly to user queries and quality assurance is in place to maintain agreed standards.

However, the quality of the service becomes irrelevant if the user cannot pass the first step and locate their information. Most users are indifferent to the source of their documents and want quick and easy access to resources. A comprehensive database or seamless access to multiple databases with a single interface assists users with that process.

The potential advantages for libraries include a reduction in ILL workload, improved turnaround time, fill-rate and user satisfaction, but the issues relating to unmediated document delivery must be assessed and managed or libraries will not experience these advantages. The service must be promoted, users and library staff trained, efficient financial management established, the supplier/s should meet pre-determined criteria, and the library should consider the inter-operability of systems and the possible influence of copyright laws and licence agreements.

Hybrid libraries which combine access and ownership models are already a reality with the reduction of print material and an increase in online services. While document delivery suppliers and publishers have become involved in document supply, libraries still play an important role in the provision of information to their users by ensuring the quality of unmediated services. However, they will need to promote this role to their users if they want to maintain their profile as an information provider.

It is unlikely that traditional ILL services will be completely replaced by unmediated services for some time as ILL staff have valuable expertise in locating grey literature and tracking incomplete references. But as the quality and flexibility of unmediated services improve, more libraries will use them to complement their traditional ILL services. The future role of unmediated document delivery is dependent on technological developments, the establishment of information gateways, changes to licensing agreements, and partnerships with publishers and suppliers. If these developments come to fruition unmediated document delivery services will evolve into mainstream library services and libraries will rapidly (and necessarily?) advance towards an access model of information provision.
