UNIMAS Library provides public access through its PeTARY membership scheme, which aligns with the categories in your question: automatic free access, access to all after application, and access in some circumstances. Some groups receive automatic free access, such as pensioners who can use reference services without annual fees. Most public users, including external individuals, government officers, alumni, and students from other institutions, receive access after application, where they register and pay a small fee (e.g., RM5 registration for external users or annual fees for borrowing). Meanwhile, access in certain circumstances is reflected in day-use options where the public can access library resources for a RM20/day reference fee, as well as corporate or institutional memberships that allow access under specific organisational arrangements.

UNIMAS Library and its branches are vital components of the university, providing essential information resources, services, and facilities that support learning, teaching, and research, while also extending public access through mechanisms such as automatic free access for certain groups, application-based memberships for general users, and conditional access options like day-use or corporate arrangements to ensure wider community engagement.
