Effective September 1, 2017 the LDS Family History Center will no longer loan microfilm to its affiliates (SNO is an affiliate). The supply of unexposed microfilm and duplication equipment has forced them to make this decision. For more details about the reasons, please see their website.
But on the upside, there are some amazing digitization efforts going on and you will see that content on FamilySearch.org. For more information about the decision and the implications, please check the FAQ on the FamilySearch.org website.
