They used to be called Family History Centers. They are "branches" of the FamilySearch Library, the world's largest genealogy library, located in Salt Lake City, Utah, USA. FSCs are free facilities, usually located in a church building or occasionally in a public library. You will find knowledgeable people there, willing to offer suggestions to help you with your research. The parent organization is FamilySearch (https://www.familysearch.org/) financed by the Church of Jesus Christ of Latter-day Saints, but FSCs are open to everyone of all faiths, and you are not asked to identify your religious faith.
There are over 6,500 FSCs scattered around the world. To find the ones nearest to you use this link
