FamilySearch uses sources that include family genealogies, historical records, a catalog of published materials, and various books and publications to provide information about family history. The organization maintains the world's largest database of genealogical and historical records and operates thousands of information centers around the globe.
FamilySearch uses family genealogies that are submitted by users and then collated to link various lineages. When searching for an ancestor, records can be filtered to show death certificates, marriage licenses and birth certificates. Data from the U.S. Census Bureau is included in search results. The catalog of materials includes microfiche, microfilm, online sources, books and other publications. Sources can be restricted by type, location, film or batch number.
The FamilySearch website offers a feature that allows users to browse all published collections. It provides links to a library network called WorldCat and a collection of archives called Archive Grid. The site also boasts a family history research wiki that allows users to access over 80,000 articles about where to find various record collections.
FamilySearch also offers other services, including digitizing and preserving images and records, web hosting and online indexing. The organization was previously called the Genealogical Society of Utah, and it has been collecting and maintaining information for over 100 years.
