<![CDATA[ The SNI Corner service in higher education libraries is an important source of standardization information for students, lecturers, and the general public. However, the effectiveness and efficiency of this service need to be evaluated to ensure its quality and relevance to user needs. This study aims to: 1. Identify the evaluation of input for the SNI Corner service, 2. Explain the evaluation process of the SNI Corner service, and 3. Describe the evaluation output of the SNI Corner service at the Riau University Library. This research employs a qualitative approach with a descriptive method through data collection techniques including interviews, observations, questionnaires, and document studies. Data sources were obtained from the Sub-Coordinator of Services, administrative staff, and library users at Riau University. This study uses the System Analysis Evaluation Model, also known as the Management Evaluation Model, with stages of input, process, and output. The overall results of this study indicate that the SNI Corner service at the Riau University Library is functioning well and effectively. However, there are still some shortcomings in its implementation. In the Input stage, aspects that are not yet optimal include activity planning and human resources. In the Process stage, the aspect that is not yet optimal is the absence of a specific Standard Operating Procedure (SOP), and promotional activities have not been optimally implemented. In the Output stage, the aspect that is not yet optimal is user satisfaction surveys, suggesting the addition of SNI Corner service components to the survey materials.]]>
