Which term best describes yearbooks in library terms?

• A. Nonperiodical serials
• B. Annuals
• C. Periodicals
• D. Monographs

Answer: (D)

In library terms, the key distinction is whether a publication is a continuing series (periodical/serial) or a standalone work (monograph). A periodical is issued regularly in separate issues over time, forming a ongoing sequence. A monograph, by contrast, is a single work or a complete unit that stands on its own, even if new editions appear later.

Yearbooks fit the monograph class because each edition is a complete, self-contained publication with its own title page, contents, and bibliographic record. Even though a new year’s yearbook comes out each year, each volume is treated as its own bibliographic unit rather than as a continuing set of issues within one title. That makes them best described as monographs.

The other terms describe different publication patterns: periodicals are ongoing, multi-issue series; annuals can describe yearly outputs but are typically considered the form or frequency rather than a single bibliographic unit.
