magazine
A periodical publication other than a newspaper, usually devoted to a subject and issued weekly or less frequently.
A magazine is a periodical other than a newspaper. Magazines usually cover some particular theme or subject, although they may also focus on news in general or some other highly general scope of content. They are usually published on a weekly or less frequent basis.
A particular theme is usual without being required; a magazine can have a broad news scope. The recurring publication form distinguishes it from a separately published book.
A newspaper has the separate frequent, general-news definition. An academic article published in a journal is classified within the magazine source type under the academic paper rule.
