The materials are listed in eight categories: (1) Encyclopedias and Handbooks; (2) Yearbooks and Annual Reviews; (3) Almanacs and Directories (general and government programs and services); (4) Statistics; (5) Dictionaries; (6) Biographical Sources; (7) Indexes (general, periodical, newspapers and current awareness surveys, government documents, and theses); and (8) Topical Bibliographies and Surveys (general bibliographies, arms control and disarmament, civil/human rights, the constitution, elections, external relations, intergovernmental relations, nationalism, native peoples--government policy, political parties, public administration and finance, and women). Information provided for each item includes the author, publisher, publication date, call number, and a brief annotation. (KRN)
