NOTE: The large centers, previously called multi-stake or regional centers, are now called FamilySearch Libraries.
As of September 2018, there are more than 5,100 FHCs in 140 countries. There is no cost to visit a Family History Center or FamilySearch Library. They are open to anyone with an interest in genealogical research. They are operated by The Church of Jesus Christ of Latter-day Saints. [https://www.churchofjesuschrist.org/].
