What does ISBN mean?
ISBN is the International Standard Book Number. This number clearly identifies books and other editorial publications such as audiobooks, software, maps, brochures, etc.
ISBN numbering is assigned only once. If a new edition appears or a book is published in a new form such as paperback, hardcover or softcover, it needs a new ISBN encoding. The only exception to this rule is unchanged reprints.
Does every book publication need an ISBN number?
An ISBN number can be obtained in Germany from MVB Marketing- und Verlagsservice des Buchhandels GmbH. The allocation of such a label is subject to a fee. Nobody is obligated to the marking. Nevertheless one should think in time whether these costs are worthwhile for one, because with the help of the ISBN number books can be found more simply or ordered in the book trade.
Where should the ISBN number be displayed?
The ISBN identification must be printed clearly visible both inside and outside the book. For this reason, it is important to apply for the number before the printing phase.
Identification on Amazon
At Amazon, almost all products offered are marked with an ASIN (Amazon Standard Identification Number). This is an individual code by which the respective article can be identified. Books are a special exception, as the ASIN here corresponds to the respective ISBN number of a book.
Books can easily be found at Amazon by entering the ISBN number at the top of the search box. The ISBN number is displayed on Amazon in the Product Information section.
