Borrowing special materials
Audio-visuals, such as DVDs, CDs, audiocassettes, 16mm films, etc., are sometimes difficult to borrow through Interlibrary Loan. Many libraries do not loan this type of material at all. ILL users are welcome to request educational audio-visuals, but please understand the date of receipt cannot be determined with any degree of accuracy, and it may be difficult to identify a lender. For these reasons, ILL does not schedule, or "book" audio-visuals for classroom showings. Faculty interested in this type of service should contact staff in the Media Center, who will consider purchasing the needed item for ISU's collection.
Obtaining dissertations & theses
Most major American universities participate in the ProQuest (formerly University Microfilms International, or UMI) program for reproduction of dissertations. The ISU Library provides full text access to most U.S. doctoral dissertations. If a thesis or dissertation is not available from ProQuest, submit an ILL request to borrow as a book.
Serials in microform (journals, newspapers, etc.)
Some researchers find it necessary to borrow numerous issues or years of a serial title. Oftentimes this is for historical research in a newspaper. In cases such as this, ILL staff will attempt to borrow the material in microfilm or microfiche, as libraries normally do not loan paper volumes/issues of newspapers and journals. When requesting to borrow microforms, submit separate requests for non-contiguous spans of years. For instance, if the years 1995 through 1996 are needed, the request can be submitted on one form by indicating 1995-1996. If the years 1965, 1977, 1988-1989 are needed, three separate requests should be submitted. Interlibrary Loan staff will attempt to borrow the paper version of the serial only if a microform is not available.
Items from the Center for Research Libraries (CRL)
Through the Library's membership in the Center for Research Libraries (CRL) in Chicago, borrowers receive the benefit of several services, including no-charge access to more than 3.5 million unique bibliographic items, extended loans of materials from the Center's collections, microform loans, the loan of some foreign dissertations, serial loans, and photocopies.
