The books in this series contain reprints of articles, excerpts from books, addresses on current issues, and studies of social trends in the United States and other countries. There are six separately bound numbers in each volume, all of which are usually published in the same calendar year. Numbers one through five are each devoted to a single subject, providing background information and discussion from various points of view and concluding with an index and comprehensive bibliography that lists books, pamphlets, and articles on the subject. The final number of each volume is a collection of recent speeches. Books in the series may be purchased individually or on subscription.
