Periodical literature

Periodical literature (singularly called a periodical publication or simply a periodical) consists of published works that appear in new releases on a regular schedule (''issues'' or ''numbers'', often numerically divided into annual ''volumes''). The most familiar example of periodical literature is the newspaper, but the magazine and the academic journal are also periodicals, as are some modern websites, e-journals, and other electronic-only publications produced recurrently on a schedule. Periodical publications cover a wide variety of topics, from academic, technical, and trade, to general-interest subjects such as leisure and entertainment.

Articles within a periodical are usually organized around a single main subject or theme and include a title, date of publication, author(s), and brief summary of the article. A periodical typically contains an editorial section that comments on subjects of interest to its readers. Other common features are reviews of recently published books and films, columns that express the authors' opinions about various topics, and advertisements.

A periodical is a serial publication. A book series is also a serial publication, but is not typically called a periodical. An encyclopedia or dictionary is also a book, and might be called a serial publication if it is published in many different editions over time. A periodical series, such as a journal series, is a sequence of journals having certain characteristics in common that are formally identified together as a group (). Provided by Wikipedia
