Departments should consider alternative means of accessing research material, particularly where an item is not likely to be consulted often, or when an expensive journal will remain largely unread. Direct charges to users of this service are kept as low as possible. 9.2 Document delivery services . Some of the on-line bibliographical services available to members of the University offer document delivery services. Documents may be delivered by fax, first-class post, or by email.
Charges vary and are paid directly by the end-user.
9.3 Electronic information . Information about these and similar resources is available on the Library's WWW pages, or from the appropriate Link Librarian. An important issue with such resources is their long term availability. The Library will look towards suppliers of electronic resources with clear archiving strategies , which guarantee long term access to this material for University users. This will be a major criteria in the decision to subscribe to such services.
