Material
found in special collections is vast and varied. It's usually
rare, old, and aesthetic. A collection could consist of not only
books, but papers, maps, film, photographs, sound recordings,
and ephemera.
Since
this material has artifactual value, it's uniqueness is what is
being preserved, if at all possible.
So
many types of media...so many ways
to preserve them.
Everything
I ever wanted to know about preservation I found out about in
Kristen St. John's class.
