What is ISBN (International Standard Book Number)?

An ISBN (International Standard Book Number) is a 13-digit number used to uniquely identify a book. Once assigned to a publication, the ISBN may not be changed, replaced, or re-used. ISBNs consist of 13 digits: the 3-digit prefix 978, denoting a book-type product, followed by a 9-digit main element, and lastly a check digit, which is a single-digit Arabic numeral for validating the rest of the number. 

The registration group identifiers used in Estonia are 978-9916-, 978-9949- and 978-9985-.

What is the difference between ISBNs, ISMNs, and ISSNs?

ISBNs and ISSNs are used as identifiers of books and periodicals respectively. ISBNs are assigned to all single- or multi-volume books as well as non-book publications which are not published as an open-ended series.

Book series and serial publications not published under a common title are given both standard numbers. Each issue of a serial publication receives a unique ISBN number, while the ISSN remains the same as long as there are no changes in the name of the publication.

The ISMN is the international standard music number, which is issued for musical scores.

Location of ISBN in a book

The ISBN appears in the lower-left corner of the back of the title page of the book, (in at least a 9-point font), as well as at the bottom of the outside of the back cover. The ISBN must also be legible on the barcode of the product. For audiovisual and electronic publications, the ISBN is printed on both the storage medium and its cover. Each annex to a book must have its own ISBN. If a book has two or more ISBNs, they must all be printed on the reverse of the title page. In the case of a multi-volume book, the ISBN of the full book appears first on the reverse of the title page, followed, underneath it, by the ISBN of the specific volume. Only the ISBN of the volume is printed on the back cover of the book.
