Donor Restrictions
Access to some material held by the Archives is restricted due to donor request. In some cases, restrictions can be waived with donor agreement. The researcher is responsible for drafting a letter to the donor (or the heir of the donor's estate) explaining why access to restricted material is being sought. The Archives will act as liaison in this process.
Conservation Restrictions
Conservation considerations may result in restricted access to archival documents. For instance, some early CNE programs are too fragile to handle and some types of film cannot be viewed on a projector without causing damage.
Restrictions on Unprocessed Records
Access to some unprocessed records may be restricted until a proper inventory can be completed and physical and intellectual control established over the records.
