T hroughout the 1990s, libraries experimented with allowing their users to order articles directly from commercial document suppliers and subsidizing the resulting costs. Permitting the user autonomy in obtaining articles can potentially affect three major areas of library operations: collections, services, and staffing. To a large extent, timely access to nonsubscribed journals expands the collection and does so faster than interlibrary loan. In an era of highly inflationary serials, another benefit of unmediated document delivery is that it can soften the blow of journal cancellations by streamlining the process for obtaining articles. The need for specialized information can be met rapidly and economically through document delivery rather than subscribing to journals desired by a limited population. From a service aspect, unmediated document delivery provides for speedier access to information than traditional interlibrary loan because it eliminates the "middleman" and thus decreases processing and delivery time. Ordering articles for themselves offers a convenience to those users who prefer to take charge of their own document delivery needs or are under severe time constraints. Unmediated document delivery appears to offer a means to reduce interlibrary loan operational expenses, salaries, and staff workloads by transferring the ordering and receiving processes to the requestor.The constant changes in services and delivery methods that are provided by document suppliers call for a re-evaluation of methods and effectiveness of unmediated document delivery. In this article, we identify reasons for trying unmediated document delivery, evaluate its success or failure in meeting expectations, and present considerations for deciding when using unmediated document delivery is advantageous.
ProceduresWe will describe a recent unmediated document delivery project at the University of Nevada, Las Vegas (UNLV), from the planning of a pilot project to the implementation of a new service. Information gathered regarding usage and
