In general, the title of a work is recorded just as the words appear in the publication.
A book normally has one title. But, books may contain chapters or sections with individual titles. Or, a book may be part of a series (6.29) or a single volume in a set. When citing a chapter out of a book include the chapter title (not italicized) and the page numbers.

Journal, magazine, and newspaper titles
Articles may appear in print or electronic journals, magazines, or newspapers. The reference will contain the title of the article and the title of publication in which it appears. The words of the article title should be capitalized the same way you capitalize a book title. The periodical title should be all capitalized except for small words (i.e. a, and, the) and italicized.
