The citation usually includes the following except

A citation for a periodical article typically includes several key pieces of information to help readers locate the source. Let's examine each item listed:

• i. Title of the article: This is essential for identifying the specific work.
• ii. Title of periodical: This identifies the journal, magazine, or newspaper where the article was published.
• iii. Date of periodical issue: This is crucial for locating the specific issue of the publication.
• iv. Page(s) on which the article appears: These are necessary for direct access to the article within the periodical.
• v. Alphabetical list of authors, titles or subjects: This describes an index or a bibliography, not a component within a single citation. A citation lists the author(s) of that specific article, not a general alphabetical list.
• vi. Volume and issue number of the periodical: These are vital for precisely locating articles in academic journals and magazines.
• vii. Author's name (or names, if there is more than one): This attributes the work to its creator(s). However, the description itself notes, "Some news items may not have names." This indicates that the author's name is not always included in every citation.

The question asks for the item that is usually included except for one. While item 'v' is fundamentally not a part of a single citation, it is not offered as an option. Among the given options (i, iii, iv, vii), the description for item 'vii' explicitly states a condition under which it might be absent ("Some news items may not have names"). Therefore, the author's name is the most appropriate answer among the choices provided as something that is not always included.

The correct option is D.
