Methods of assessing performance and value, with emphasis on evaluating each system or service in its context. Specification of criteria, measures, measuring instruments, and methods of evaluation related to a variety of library services, and to information retrieval (IR) systems.

Students will investigate the range of evaluative methods used in library and information science to assess institutional, system and service performance. Value issues and external validity issues will be highlighted during this review. Emphasis throughout the course will be on the impact of systems and services to end-users.

Measurement issues will be explored as they relate to evaluation goals and objectives. Students will simulate the design of an evaluation program for targeted users and will analyze the results obtained using quantitative and qualitative research methods. Effective methods for graphing data results will be emphasized for this objective. Computer packages will be used to demonstrate data analysis and the creation of graphic displays. Computer laboratory sessions will be held as needed to supplement the course topics.

Alternative methods to evaluate services and systems will be explored with a concomitant analysis of the advantages and disadvantages of each approach. Specific references will be made to the appropriateness of different evaluative methodologies and criteria.
