The Application of the Usability Approach in Libraries and Information Centers for Resource Selection and Deployment

Abstract

Libraries and information centers most often rely on published reviews, vendors' demonstrations, brief visits to local sites, or word of mouth to select resources for in-house or public use. The usability approach developed in the field of human computer interaction (HCI) strives to test the ease of use, user satisfaction, and effectiveness of software, hardware, and information products for a range of users. To understand how users interact with products, usability analysts employ methods from task analyses and rapid prototyping in informal settings to talk-aloud protocols in specially equipped usability laboratories. For example, OCLC and Lexis-Nexis have maintained usability laboratories for several years to assist in the design of their software products. The application of the usability approach for research in information studies and to support library and information center purchase and implementation decisions holds much promise. This work presents an overview of the major methods of usability analysis and indicates how they can be used efficiently and effectively by information professionals in real work environments to improve selection and deployment of hardware, software, and information products. Also included is a discussion of the current and future role of usability in the formal education of information professionals.
