Heinlein’s Juvenile Novels [PDF ebook] 
A Cultural Dictionary

Robert A. Heinlein’s early, juvenile science fiction novels appeared between 1947 and 1963, just as America was emerging from World War II and entering the space age, and are among his richest and most warmly remembered books. This comprehensive work defines the many names, terms and cultural references that appear in Heinlein’s juvenile novels, noting where they are found, explaining their sources and tracking their occurrences throughout the series. Of particular interest is the way in which Heinlein used science fiction to parallel the exploration of outer space with the settlement of the North American continent. Appendices provide a precis of the plot of each book, and speculate on some of the names and terms for which no specific reference could be found.
