Creating and Conserving the Idaho State Constitution Exhibit

UPDATE: The Idaho Constitution exhibit has been postponed until further notice. We are prioritizing the health and safety of visitors and staff above all else and look forward to rescheduling the exhibit and constitution programs in the future.

Following a successful fundraising campaign by the Idaho State Historical Society (ISHS) and the Foundation for Idaho History, the Idaho State Archives worked with the Preservation Lab at the University of Utah’s J. Willard Marriott Library to conserve the Idaho State Constitution.  The conservation process included paper conservation, removing laminate from two of the pages, surface cleaning, tear mending, tape removal, humidifying and flattening the document, and attaching a new custom binding.

ISHS partnered with Idaho Public Television to document the history of the Idaho State Constitution and the conservation work, as part of the Idaho Experience documentary series, titled Idaho Constitution Revealed.  The documents and photographs represented in the exhibit were featured in the documentary.
