Each year, the New York Public Library publishes a reading list for teen-agers. This edition of "Books for the Teen Age" contains an index by subject as well as an alphabetical index. Each general topic, such as The Global Village or Science, is followed by a list of more specific subjects. Among the subjects of interest to the teen-ager are Black America, the Changing Scene, Drugs, War and Peace, and Sports. All selections are followed by a one line annotation of the book. (RS)
