RESUMEN
The article presents a mixed-methods evaluation of regional libraries in Namibia, which incorporates three perspectives: the patron perspective (library users), the library perspective (library staff, management, and related officials), and the external perspective (including evaluators and monitoring data). Seven data collection methods were used: patron surveys, patron panel studies, focus group discussions, key informant and staff interviews, secondary data analysis, media analysis, and observations. The goal of the evaluation was to assess library performance for both formative and summative purposes by addressing evaluation questions on areas such as library services, use, and operations. Building upon the literature review of how mixed-methods approaches can contribute to library evaluation, the aim of this article is to show how a mixed-methods evaluation can be designed to examine multi-faceted library performance and to illustrate how the evaluation design allows information complementarity and can be utilized to present diverse viewpoints of the above three perspectives. The evaluation design, analysis process, and lessons learned from this study may be useful to evaluators engaged in evaluation of public services or programs (including public libraries) that examine multiple aspects of service performance and involve a variety of stakeholders.
