NRC-CISTI has formal arrangements with several international libraries whose collections compliment NRC-CISTI's strength in science, technology and medicine. Through Extended Supply Service, NRC-CISTI can supply documents of all types in all subject areas, including patents and standards. To speed response time, NRC-CISTI has made arrangements to have its partners deliver documents by Ariel and fax directly to clients. Most documents obtained from one of NRC-CISTI's partners are delivered within 72 hours.

NRC-CISTI's Extended Supply Service Partners are: the University of Alberta, the British Library Document Supply Centre and INIST.

NRC-CISTI will also obtain virtually any article, paper, report, book, conference, or thesis from anywhere in the world for you.

Sources include academic institutions, associations, government organizations, special collections, publishers, authors, and commercial document delivery suppliers. Turn around times for documents obtained from these sources range from 72 hours up to 4 weeks, depending on the source.

NRC-CISTI handles order tracking, billing and payments, copyright, control of loans and delivery of documents. Loan periods vary, based on the loan policy of the supplier.
