Multi-volume books are not considered to be serials since they are planned to be published in a limited number of volumes, even if all volumes are not issued simultaneously. Series which are intended to comprise a definite number of individual parts and loose-leaf publications intended for updating with replacement pages are also excluded.
If Australian publishers are unsure whether their publication may be eligible for an ISSN, they should contact the Australian ISSN Agency.
What is an ISSN?
The ISSN (International Standard Serial Number) is a unique code for the identification of serial publications. It can be used wherever information on serials needs to be recorded or communicated. The ISSN is the serials equivalent of the ISBN (International Standard Book Number).
