Many state and local archives, libraries, and genealogical or historical societies; the Family History Centers of the Church of Jesus Christ of Latter-Day Saints (Mormons); and other institutions have purchased all or some of the census microfilms and make them available to the public. Information on many of these institutions appears in Alice Eichholz, ed., "Ancestry's Red Book: American State, County, & Town Sources" (Salt Lake City: Ancestry Publishing Co., 1992). The National Historical Publications and Records Commission's "Directory of Archives and Manuscript Repositories in the United States" (Oryx
Press, 1988) lists over 4,000 repositories in the United States, including Puerto Rico and the U.S. Virgin Islands, many of which have copies of census microfilm. In the National Archives research rooms, the public also may request a copy of "State Archives Referral List," Form NA 14031, which lists addresses of these repositories.
