Answer: Submit an interlibrary loan request at his school's library.
Most universities have an interlibrary loan service. This is a service that allows students to borrow books, magazines, CDs, DVDs, etc. that are owned by other universities. Students can usually make such requests at their own library, which would act as intermediary. This is a service that is convenient for students and allows them to access a huge range of materials from many different educational institutions.
