ABSTRACT. San Jose State University Library, like most academic libraries, is struggling to meet users' rising expectations for immediate information within the financial confines of a flat budget. To address acquisition of non-subscribed article content, particularly outside of business hours, San Jose State University Library implemented Copyright Clearance Center's Get It Now, a document delivery service. Three academic years of analyzed data, which involves over 10,000 requests, and the subsequent collection development actions taken by the library will be discussed. The value and challenges of patron-driven, unmediated document delivery services in conjunction with traditional document delivery services will be considered.
