Periodical

A periodical is a publication appearing at regular or stated intervals, usually more frequently than annually, and containing separate articles, stories, or other writings. Periodicals include journals and magazines and collections and bulletins published in series. They are capable of exerting strong influence on public opinion. Unfortunately, good writing in periodicals is frequently forgotten. Authors writing for periodicals risk wasting their efforts on small audiences or on topical or special interest subjects, and it is sometimes difficult, for this reason, for periodicals to attract good writers. Periodicals, therefore, often contain inferior quality material.
