Fast track fees still apply if required. Part of the function of an ISBN is to uniquely locate a publisher, as well as a publication. The group of numbers at the beginning of an ISBN is the specific publisher's prefix, which determines the block of numbers, which is the publisher's own. Even when each volume is not sold separately, the allocation of an ISBN to each volume is advisable. If any part is available separately, a separate ISBN must be allocated to each part, and to the kit as a whole.
Reprints do nor require different ISBNs, while new editions do.
Paperback, hardback, CD-ROM, video, audio book etc. Single ISBN notifications are usually only faxed as soon as they are processed, or emailed or posted if you do not have a fax machine. An ISBN should be printed on the reverse of the title page of a book, along with copyright and publisher information. Many publishers also print it on the bottom-right of the back cover for ease of reference. If a book has a dust jacket, the ISBN should also appear on the back of this.
