ISBN & ISSN

International Standard Book Number

The ISBN (International Standard Book Number) is a 10- or 13-digit number that uniquely identifies books and book-like products published internationally. Each number identifies a unique edition of a publication, from one specific publisher, allowing for more efficient marketing of products by booksellers, libraries, universities, wholesalers and distributors.

The Australian ISBN Agency is now operated by Thorpe Bibliographic Services. Publishers who wish to apply for an ISBN should contact ISBN Agency Australia at the following address:
