When an annual or less frequently published serial has been cataloged as a monograph and is to be recataloged as a serial, the monograph record may contain subject headings that are valid for the serial record. Some minor adjustments may be necessary, such as adding the form subdivision " Periodicals." be careful, however, not to use headings that are too specific because they suit only a single issue of the serial.
