Access to electronic information resources is purchased under licence by the Library on behalf of the University. Exact licence terms vary from one publisher to another, but in general they authorise use of the resource by current students and staff of the institution, for the purposes of academic research. The Library also offers visitors access to a limited range of online resources, where licence agreements permit.
