ISBN and other identifiers


ISBN (International Standard Book Number) is the international standard book number. This is a unique number of the book edition which is necessary for book distribution through retail networks and work automation with the edition.

This standard was developed in the 1960s so as the LBC. In particular, it was developed in 1966 in Great Britain. The base of the 9-value Gordon Foster Standard Number was used to create this standard. ISBN has undergone a number of changes for all these years and in 2007 it became 13-valued that coincided with the barcode.

All ISBN numbers in books published up to and including 2006 consist of:

  • ISBN abbreviation
  • 10 symbols separated by a hyphen or a space for four fields.

The four code fields indicate the following:

  • Country of origin (or group of countries connected by the language of publication) that is assigned by the International ISBN Agency.
  • Code of the publishing house that is assigned by the National ISBN Agency.
  • Unique issue number.
  • Target figure (Arabic figure from 0 to 9 or Roman figure X) that is assigned by the National ISBN Agency.

ISBN is necessary to be registered for the book in the Central Institute of Bibliography.

The Ukrainian Central Institute of Bibliography ( is a state scientific institution in the publishing area and information activity. The Ukrainian Central Institute of Bibliography is also the National Agency of International Standard Book Numbering (ISBN) and the International Standard Music Numbering (ISMN) of Ukraine.

In addition, an assigned ISBN may be necessary for the author of the book if he would like:

  • to join the Society of Authors or another literary organization
  • to defend a doctoral or Ph.D. thesis
  • to distribute his book through retail networks.


ISSN (International Standard Serial Number) is an international standard serial number. It serves for periodicals numbering and makes it possible to identify any serial edition, regardless of where it is published, what language and on what medium. The number consists of 8 figures.

ISSN number is necessary for effective international distribution of the publications as well as for ISSN barcode creating for trade automation.

Any periodic publication can get ISSN if it is internationally distributed. This can be a newspaper, a weekly publication, a journal, a yearbook and even an electronic publication (CD, website). The fundamental criterion is the periodicity which means that the component parts of the publication are published as an open set of documents with the same title, period and for indefinite time.

Author Mark

The author mark is an identification mark of the author's last name or the first word of the title of the book. It consists of one letter and two figures. The letter is the first name of the author or title. Two figures are determined by special tables, and two-figure number is derived from the sequence of the first letters of the last name or title of the book.

The author mark was introduced by Lyubov Khavkina, the well-known specialist of the library science in 1916.

The author mark is in the upper left corner of the copyright page under the LBC identifier in books.
