### Abstract
This study aimed to assess the adoption and usability of library portals in Zambian universities. The research objectives were threefold: first, to determine the extent of adoption of library portals in Zambian universities; second, to assess the integration of key library portal features; and third, to examine users' perceived usability of these portals. A mixed-method design was employed, including questionnaires distributed to the 62 universities registered under the Higher Education Authority (HEA) to collect their URLs. A heuristic evaluation was conducted to assess portal characteristics, involving 12 expert librarians as participants. Additionally, a System Usability Scale (SUS) was utilized to gauge the perceptions of lecturers and students towards the portals, with a sample of 20 lecturers and 304 students. The findings revealed that only three Higher Education Institutions (HEIs) in Zambia had adopted library portals: ZCAS University, Mulungushi University, and the University of Zambia (UNZA). The study indicated that participants generally rated the usability of these portals as average. Specifically, the average SUS scores for UNZA (n=132, SD=53.685), ZCAS (n=68, SD=60.28), and Mulungushi (n=124, SD=51.865) were all above the 50 SUS score threshold. Despite being categorized as 'Ok' according to the SUS scores, the study emphasized that this rating falls within the marginal acceptability range. The results underscored the limited presence of library portals in Zambian HEIs and the need for universities to prioritize the redesign of their existing portals to enhance information provision and overcome distance barriers. Furthermore, the study recommended that the three universities with library portals focus on improving their platforms to encompass all essential characteristics of effective library portals.
