You can request articles from journals, conferences etc that the library does not have by using the Inter Library Loan Service.
Articles via ILL will usually be supplied by the British Library in SED (Secure Electronic Delivery) format using a link that will be sent to you by email. Only in exceptional circumstances can requests be made specifically for a photocopied version. There will be an additional charge of £1.50 to do this, making the total cost for the request £3.00. Please discuss your requirement with Library staff.
