Articles in periodicals are also the best source of information for reading about recent events and topics of current interest. The terms serials, periodicals, magazines, and journals are often interchanged, and their distinctions are not always clear. Serials is the broadest term for these type of publications. Serials are any publications that are issued in parts over an indefinite time period. They include periodicals but also proceedings, annuals, and irregular publications.
Periodicals are publications that are issued in frequent regular intervals.
They include magazines, journals, and newspapers. The distinction between magazines and journals is small but can be important. Generally magazines are considered to be of popular interest. Journals are considered to be of scholarly or professional interest. Newspapers are really little different from other current event magazines, except that some come out daily, and come in the familiar newsprint format.
