Multiple copies may be purchased
for high demand titles and/or titles authored by MSU faculty.
Replacement copies may be ordered,
as funds permit, for missing or damaged heavily-used titles or parts of
multi-volume works.
Out-of-print materials are not
normally considered for purchase, unless there is a compelling need for a
unique item that has been officially classified as missing or damaged beyond
repair.
Materials no longer needed for the
collection are de-selected as identified.
Preservation decisions follow the
general guidelines established by the Main Library.
