Preface Special lists are published by the National Archives and Records Service (NARS) as part of its records description program. The special list describes in detail the contents of certain important records series; that is, units of records of the same form or that deal with the same subject or activity or that are arranged serially. Its form and style are not fixed but vary according to the nature of the records to which it relates. Its distinguishing characteristic is that it goes beyond the general description contained in a record group registration statement, a preliminary inventory, or an inventory and describes records in terms of individual record items. In addition to lists and other finding aids that relate to particular record groups, NARS issues publications that give an overall picture of materials in its custody. A new, comprehensive Guide to the National Archives of the United States and a revised and expanded Guide to Materials on Latin America in the National Archives of the United States were published in 1974. Reference information papers analyze records in the National Archives of the United States (hereafter called the Archives) on such subjects as transportation, small business, and the Middle East. Records of the Civil War are described in Guide to Federal Archives Relating to the Civil War (1962), Guide to the Archives of the Government of the Confederate States of America (1968), and Civil War Maps in the National Archives (1964); those of World War I in Handbook of Federal World War Agencies and Their Records, 1917- 1921 (1943); and those of World War II in the two-volume guide Federal Records of World War II (1950-51). Genealogical records are described in Guide to Genealogical Records in the National Archives (1964). In the Archives are large quantities of audiovisual materials received from all sources: Government, private, and commercial. The Guide to the Ford Film Collection in the National Archives (1970) describes one of the largest private gift collections. The extensive body of maps and charts is described in the Guide to Cartographic Records in the National Archives (1971). Many bodies of records of high research value have been microfilmed by NARS as a form of publication. Positive prints of these microfilm publications, many of which are described in the current Catalog of National Archives Microfilm Publications, are available for purchase.
