This study examined the perception, use, and effectiveness of open source library systems by academic librarians in selected institutions in Kwara State, Nigeria. Fifty-eight librarians drawn from five academic libraries represent the sample for the study. The research adopted a descriptive survey approach, using a questionnaire to gather data to test five aspects of use and perception. The findings show that most of the respondents perceived open-source library systems as effective for handling academic libraries' services; the effectiveness of the open-source systems from the librarians' perspective depends on its practical usability and efficiency. Librarians profile such as position/designation, educational level, years of experience, and gender affect the perception of open source system OSS; while erratic power supply, lack of funding and equipment are the most common challenges faced by libraries and librarians concerning the use of open-source library systems. Observation from the literature reveals that there are published researches on open source, however, there is a need for more research in this area concerning Nigeria's academic libraries. Furthermore, most of the published studies consider various aspects of the adoption process, reasons for adoption, the process of training and maintenance, and not perception which is an important factor that determines use. This study provides a significant potential to explore the effectiveness of open source library systems in academic libraries by academic librarians in tertiary institutions libraries in Nigeria. The findings of the study add to the existing literature to provide a better understanding and creating awareness on the best practices in the application of open-source library systems to library operations.

这项研究调查了尼日利亚夸拉州选定机构中的学术图书馆员对开放源图书馆系统的理解，使用和有效性。来自五个大学图书馆的58名图书馆员代表了该研究的样本。该研究采用描述性调查方法，使用问卷收集数据以测试使用和感知的五个方面。调查结果表明，大多数受访者认为开源图书馆系统对于处理高校图书馆的服务是有效的。从图书馆员的角度来看，开源系统的有效性取决于其实际的可用性和效率。图书馆员的个人资料，例如职位/职务，学历，工作年限和性别，都会影响对开源系统OSS的看法；电源不稳定，缺乏资金和设备是图书馆和图书馆员在使用开源图书馆系统方面面临的最普遍的挑战。从文献中的观察表明，已经有关于开源的公开研究，但是，在这一领域中，需要对尼日利亚的学术图书馆进行更多的研究。此外，大多数已发表的研究都考虑了采用过程的各个方面，采用的原因，培训和维护的过程，而不是感知是决定使用的重要因素。这项研究提供了巨大的潜力，可以探索尼日利亚大专院校图书馆的学术图书馆员对开放式图书馆系统在高校图书馆中的有效性。
