Print format books are available by searching the NSU online catalog (see the "NSU Libraries Home Page" link below).
Searches may be limited to just the Broken Arrow campus for convenience. Books available on the Tahlequah campus may be ordered for delivery to the Broken Arrow campus. It usually takes two to three days for materials to arrive via inter-campus mail.
Electronic books: EBSCO provides access to over 25,000 academic books to NSU students 24/7 (see the link below).
Materials unavailable at any NSU library may be obtained via Interlibrary Loan (ILL). Interlibrary loan is a free service that allows NSU patrons to borrow materials from other libraries.
Articles are delivered electronically and typically arrive within two days of placing the request. Allow approximately two weeks for books and other physical materials to be received. Be aware that requests are usually filled quickly, but can sometimes take longer. Request ILL items early! Check out the below link to access your interlibrary loan account.
