THE GUIDE TO Depositories of Manuscript Collections in Illinois ( Chicago, 1940), based on work by the Historical Records Survey in the late 1930s, briefly described the holdings of only forty institutions in the state. In 1978, the National Historical Publications and Records Commission issued the Directory of Archives and Manuscript Repositories in the United States, which, as partly updated ( 2nd ed., Phoenix, Ariz., 1988), identified in Illinois 180 historical societies, governmental agencies, college and university libraries, and other institutions engaged in preserving the primary sources of history, and this work is only a recent addition to a shelf of directories to which students of Illinois history may turn in their research. Local historical societies are listed by the American Association of State and Local History in Mary Bray Wheeler, ed., Directory of Historical Organizations in the United States and Canada ( 14th ed., Nashville, Tenn., 1990) and by the Congress of Illinois Historical Societies and Museums in Historical and Cultural Agencies and Museums in Illinois ( latest ed., Springfield, 1989). The American Library Directory. . . ., now in its 43rd edition ( 2 vols., New York, 1990), is useful for public and special libraries and for some data as to the holdings of each institution. Many libraries provided a list of their collections for the Illinois Regional Library Council's Illinois Libraries and Information Centers, edited by Ellen Palmer ( Chicago, 1981).
Regional directories have supplemented national and state listings in recent years. The most successful publication of this kind was issued by the Chicago Area Archivists, Archival and Manuscript Repositories in Metropolitan Chicagoand the Calumet Region of Northwest Indiana
