James Gilbert Ryan & Leonard C Schlup 
Historical Dictionary of the 1940s [PDF ebook] 

The only available historical dictionary devoted exclusively to the 1940s, this book offers readers a ready-reference portrait of one of the twentieth century“s most tumultuous decades. In nearly 600 concise entries, the volume quickly defines a historical figure, institution, or event, and then points readers to three sources that treat the subject in depth. In selecting topics for inclusion, the editors and authors offer a representative slice of life as contemporaneous Americans saw it – with coverage of people; movements; court cases; and economic, social, cultural, political, military, and technological changes. The book focuses chiefly on the United States, but places American lives and events firmly within a global context.
