journals are called periodicals because they are issued on a regular
or "periodic" basis (usually more frequently than once a year.) Periodicals are usually separated
into three major groups: popular, scholarly/research, and trade/professional. If you

source, you can focus your research to retrieve only the type of
articles you need.
