The Systems and Procedures Exchange Center (SPEC) surveyed Association of Research Libraries (ARL) institutions to measure the degree of electronic resource sharing in ARL libraries; to discover which resources are being shared and between what kinds of institutions; and what documentation is available. Of the 119 ARL institutions surveyed, 53 responses were received, out of which 39 institutions completed the entire survey and reported sharing electronic resources. Data revealed that 46% of responding institutions implemented electronic resource sharing in the last 1-3 years. The most frequently shared electronic information resource is the tape-loaded index. The most frequently cited motivations to share were "enrichment of resources available to all participants" (97%) and"cost" (87%). Improved technology and the desire to test technical capabilities were also important motivations. Generally, costs of subscriptions and telecommunications are borne by individual institutions, while one institution maintains the database. Change in the area of electronic resources is occurring more rapidly than in any other area affecting libraries. Survey results are followed by a list of responding institutions, a description of selected electronic resource sharing groups, a consortial agreement from North Carolina State University, and an alphabetical listing of electronic research databases at Ohio University.
