8. The registrant and the publisher element The second part of the ISBN identifies a particular publisher within a group. The publisher identifier usually indicates the exact identification of the publishing house and its address. If publishers exhaust their initial contingent of title numbers, they may be allocated an additional publisher identifier. The publisher identifier may comprise up to seven digits. 70002Example: ISBN 90-70002-...

9. The publication element or Title identifier The third part of the ISBN identifies a specific edition of a publication of a specific publisher. A title identifier may consist of up to six digits. As an ISBN must always have ten digits, blank digits are represented by leading zeros. 04Example: ISBN 90-70002-04.
