A dramatic increase in interlibrary loan (ILL) in academic and research libraries in the last five years, combined with a changing office environment, is forcing reassessment of the relationship between the volume and cost of loans to service quality. In the spring of 1988, a survey was sent to 116 member libraries of the Association of Research Libraries (ARL) to gather data about workload, professional and non-professional staffing levels, use of bibliographic utilities, fillrates, and perceptions about staffing adequacy. This report uses the 76 responses received to present an overview of ILL staffing patterns, test assumptions about workloads and fillrates, and suggest some guidelines for libraries to follow in the analysis of their own efficiency and effectiveness. In conclusion, it is suggested that the importance of professionals in ILL may be underestimated, and that increasing ILL activity may be causing a reduction in the quality of service in borrowing operations. Six tables highlight survey responses. Appended are a copy of the survey and cover letter; a self-analysis workform showing median productivity levels for libraries found to be effective and efficient in ILL operations; and linear and quadratic correlations and a chart for monthly analysis of unfills.

Consortia and other library partnerships are now sharing ever larger fractions of their collections, and this book gives library staff the tools necessary for a smoothly functioning ILL system.
