Michigan Historical Collections

Michigan Historical Collections (MHC) materials are typically open to the public unless the donor(s) have imposed specific access restrictions on them in the gift or deposit agreement. If such restrictions have been requested, then that material is generally restricted until December 31st of the year noted in the gift agreement.

In select cases, such as with congressional collections, specific regulations or statutes may require the processor to impose slightly different access restrictions. For example, in compliance with Senate Resolution 474, committee records are restricted for twenty (20) years from the date of creation, unless previously made public by the committee; and records related to an investigation, for example, the Permanent Subcommittee on Investigations (PSI), and executive nominations are restricted for fifty (50) years from the date of creation.

Twice a year (shortly after January 1 and July 1), the Lead Archivist for Collections Management reviews and unpublishes expired access restriction notes in ArchivesSpace.
