Interlibrary Loan (ILL) & Document Delivery Services (DDS)are important services to access literature for research and private study beyond our collection. The Library will source the literature via our partners, agencies, and libraries around the world, and provide access to the requested literature as soon as practicable.
ILL refers to borrowing of books, conference proceedings, or other returnable materials for a period on behalf of eligible users; while DDS refers to obtaining a copy of journal articles, book chapters, conference papers, or other materials on behalf of eligible users.
