Introduction to Genealogy While many diverse groups visit NARA's facilities nationwide and sample the agency's records, genealogists no doubt are the most numerous users of NARA's research rooms in Washington, DC, and the 12 regional archives. NARA, therefore, continues to make special efforts to satisfy the needs of genealogists. A. Genealogy holdings NARA offers the public many free general information leaflets (GILS) regarding its records of genealogical value. A discussion below briefly describes the four GILS of most importance to genealogists. Also, NARA distributes Aids for Genealogical Research, a free brochure describing NARA or commercial works that focus on genealogy. This brochure, for example, briefly explains NARA's three most important genealogical holdings--census, military, and immigration and passenger records--discussed below; notes mail-order forms and genealogy workshops and courses; and lists NARA's 12 regional archives. Copies of the GILS and sales brochure are available in the National Archives Building, Room G-9. Or, researchers may contact NARA's Fulfillment Center (NEDC), 8700 Edgeworth Drive, Capitol Heights, MD 20743-3701. Phone: 301-763-1896 ie 1-800-788-6282/ fax 301-763-6025.
