The study examines the acceptance and satisfaction with the Academic Collection of Comprehensive Educational Studies System (ACCESS), a web-based digital repository designed to enhance research accessibility and utilization in a state university in the Philippines. Using a quantitative research approach, the study applies the Technology Acceptance Model (TAM) and ISO/IEC 9126 software quality criteria to assess functionality, reliability, usability, and overall satisfaction. A random sampling technique included students and faculty members from five courses. Data was gathered through an online survey with a standardized questionnaire and a 5-point Likert scale. Findings indicate that functionality significantly impacts satisfaction and reliability, while usability enhances user experience. However, system stability issues undermine user trust and long-term adoption. Additionally, limited content availability and navigation challenges hinder full engagement. Statistical analysis revealed overlapping concepts affecting validity, likely due to response biases such as straight-lining. Despite its potential as an academic repository, ACCESS requires improvements in system stability, content updates, and usability to enhance user satisfaction. The study underscores the need for continuous evaluation and improvement of digital archiving systems to foster institutional research culture. Future research should expand the sample size and compare ACCESS with similar systems to refine its functionality and usability.
