    This study examines the system architecture and capabilities of commercially available OpenURL link resolvers. These emerging technological tools are designed to increase use of library collections by automating the process of locating and accessing library holdings. Data for the study, largely experiential feedback received from libraries employing OpenURL link resolvers, was gathered through a series of evaluative activities. These included a preliminary literature review, Web survey, follow-up e-mail survey, and on-site visits to libraries. Results were analyzed within the context of the University of Connecticut Libraries ’ resources and needs. Analysis revealed wide variation in library experiences with and perception of product functionality and

    In the thirty years from 1970 to 2000, open source software (OSS) began as an assumption without a name or a clear alternative. It has evolved into a sophisticated movement that has produced some of the most stable and widely used software packages ever produced. This paper traces the evolution of three operating systems: GNU, Berkeley Software Distribution (BSD), and Linux, as well as the communities that have evolved with these systems and some of the commonly used software packages developed using the open source model. It also discusses some of the major figures in OSS, and defines both free and open source software. ********** Since 1998, the open source software (OSS) movement has become a revolution in software development. However, the revolution in this rapidly changing field can actually trace its roots back at least thirty years. OSS represents a different model of software distribution with which many are familiar. Typically in the PC era, computer software has been sold...
