Chapters begin with a chronology of world events and a general overview of the decade. Chapters include the topics: Topics in the News, Headline Makers and Further Reading. Within each topic, alphabetically arranged entries discuss historically important events, issues, definitions of difficult concepts or terms, and other interesting trivia and sideline stories. U- X- L(R) American Decades may be purchased as a set or by individual volume; a volume-specific general index appears in each volume; and a separate, free cumulative index comes with the set.
