Table 6 illustrates how to derive the internal structure for the registration group 978 952. An

examination of the five digits following the registrant group element will permit the determination

of the length of that registrant element. Once the registrant length is known, the publication

element length can be derived.

EXAMPLE:

Test ISBN: 9789528988885

EAN.UCC prefix: 978

Registration group: 952

(registrant test segment): 89888

Registrant: 89

Publication: 8888

Check digit: 5

Displayable ISBN: 978 952 89 8888 5

Note:

 The registrant test segment is within the range from 89000 to 94999, which has a

specified registrant length of 2 (defined and valid).

5. Application of ISBN

5.1 General

A separate ISBN shall be assigned to each separate monographic publication or separate

edition of a monographic publication issued by a publisher. A separate ISBN shall be

assigned to each different language edition of a monographic publication. Where a

publication is made available to the public both individually and as part of a series, it shall

be regarded as two separate publications, each of which shall be assigned a separate

ISBN.

5.2 Changes to publications

A separate ISBN shall be assigned if there have been significant changes to any part or

parts of a publication. A separate ISBN shall be assigned if there has been a change to the

title of a publication. A change to the cover design or colour or to the price of a

monographic publication does not require a separate ISBN. Minor changes in an edition

(e.g., corrections to misprints) do not require a separate ISBN.
