For example, an encyclopedia that is issued in many volumes over a span of years is NOT a serial because the publisher has planned to issue a finite number of volumes; but a monthly journal tahat ceases after only one or two issues have been published is a serial because the original intent was to publish an issue every month.

The presence of the ISSN does not always mean that the publication is a serial. The ISSN may have been assigned to the series of which the publication is part of and not the title. If an ISSN and a ISBN (International Standard Book Number) both appear on a piece, the publication is likely to be a monograph in a series. However, the presence of an ISBN does not alone give sufficient reason to reject the publication as a serial.
