As of September of 2022, all microfilms owned by FamilySearch have been digitized and digitally preserved. The Granite Mountain Records Vault has preserved a master physical copy of each film. Every film available in the Library is a duplicate of those stored at the Vault.
In anticipation of the Salt Lake Temple open house, a few of the floors in the Library will be going through some changes. To prepare for the remodel, part of the film collection will be permanently relocated to another site. All films being relocated can be viewed digitally on FamilySearch.org while visiting the FamilySearch Library.
