Requesting textbooks through Interlibrary Loan is NOT recommended. Many libraries will not lend them, since most libraries keep textbooks on reserve for their own patrons. Additionally, books borrowed through ILL are for short-term use only. Loan periods usually are for three to four weeks. Therefore, it is not possible to keep a book borrowed through ILL for an entire semester.
