There are no typewriters in the Libraries. We don't know of any in use on campus. The UMC Reception Desk used to have one available for public use but it is long gone.
Prior to the introduction of the personal computer in the mid-1980s, these machines -- both manual (no power) and electric (powered) were widely used. The rapid adaption of the personal computer led to their drastic, dramatic, decimating decline and dodo-like disappearance.
Typewriters are primarily seen in museums of technology and in movies of a by-gone era but their spirit lives on in the QWERTY keyboards you use today.
