This online series of books prepared by the Federal Research Division of the Library of Congress presently contains studies of 100 countries. Each study has been prepared by a "multidisciplinary team of social scientists" and offers a textbook-like portrayal of the beliefs, values, institutions, geography, politics, and economics of each country. Texts include photographs, tables, glossaries, maps, and bibliographies and are dated to indicate the timeliness of the research. Most volumes were written in a timeframe spanning the late 1980s to the present, with recent volumes marked as "new."
