A periodical is a magazine published regularly, at least four times a year, which contains articles dealing with either the general or a specific sphere of life. Periodicals also include those journals in the form of newspapers which do not fulfil the criteria for a newspaper with regard to their content or frequency, e.g. trade union magazines.
