Some library resources are preserved on microfilm (reels) and microfiche (small sheets of microfilm).
The Libraries catalog will specify when an item is on microfilm or microfiche.
You can check out microfilm reels for the same amount of time you can check out a book.
Most microfilm, microfiche are located in the basement/lower level of Love North.
You can scan/copy portions of the film using microfilm readers located in the basement/lower level of Love North, or at Media Services in the Love South Link.
