Most of the larger Family History Centers provide some type of free access to a number of online subscription databases (e.g., "Ancestry.com"). Mid-range FHCs may have small local book collections. The "Ward FHC" is the smallest, consists of at least one computer, related family history programs, most likely Internet access, and has the most variable hours per week because it has a volunteer staff. The ward (single congregation) FHC may or may not have a dedicated room in the ward building ("meetinghouse"), because most buildings are designed for multiple use. Such an FHC may or may not have microfilm or microfiche readers. The "Stake FHC," which typically serves six or more ward or branch units (congregations), is the next in size and consists of two or more computers, related family history programs, Internet access, and usually offers more hours per week of service than does the ward FHC. Stake FHCs may have a small collection of CDs, books, and local historical materials. A Stake FHC usually has a dedicated room staffed by volunteers. Most have microfilm or microfiche readers and the ability to receive film/fiches from the Salt Lake City Family History Library (FHL). The "Multi-Stake FHC" serves two or more stake units consisting of eight or more wards and/or branches (congregations). These have larger dedicated areas within a stake center building, or other building, for the use of the FHC. These larger FHCs have dedicated book, microfilm, and microfiche areas. They have six or more computers with phone line, cable, or satellite Internet access, family history software, and often offer the institutional version of "Ancestry.com", "Fold3.com", and some other paid-access sites. All have microfilm or microfiche readers and the ability to receive film/fiches from the Salt Lake City FHL. Most have local area family history material, but are not "Library Class" facilities. The "Regional FamilySearch Libraries" of the Salt Lake City Family History Library are considered "library class" facilities. Each has a dedicated internal server and a library catalogs or card catalogs or online catalog for its collection. In 2010, the "regional branch libraries were re-designated as "Large Multi-Stake FHCs"" on the "FamilySearch.org" website. However a supplement to the "Family History Center Operations Guide" dated January 5, 2006, renamed these FHCs officially.
