Document Delivery/Interlibrary Loan (DD/ILL)
Our expectation with the implementation of electronic journals was that we would see a significant decrease in user requests for journal articles via our DD/ILL services. In fact, "borrowing" photocopies of journal articles from other libraries increased by 16 percent in FY1999-2000. The library's document delivery service, which provides copies of articles from the Drexel Library collections free of charge to faculty and distance learners, delivered 1,122 articles from the electronic journal collection in this same time period. The majority of these articles are for faculty who presumably are not aware of the ready accessibility of e-journals, or who either cannot or choose not to retrieve the articles themselves. At the moment, it is not possible to measure the net impact of the electronic journals on the DD/ILL department volume because too many other factors are influencing use of the service. Research activity has grown dramatically at Drexel in the past two years, and the provision of over 100 web-based databases likely has increased demand for articles. Our prediction is that ultimately we will see a decrease in net requests for this service as our users become increasingly self-sufficient and as electronic content continues to expand.
