International standard book number-exactly decrypted ISBN of the book. What it is today, I know few people who are actively interested in reading books and use them in both electronic and traditional versions. Globally this format is popular for the reason that it is the most clear, short and readable identification number, which without any difficulty at the earliest to determine any book. After such intellectual products is assigned its own unique number, it must have this format.

It is Worth noting that to date the format of the ISBN accompanies a publication from the production stage onwards. For this reason it can be called one of the most important tools in modern distribution and rationalization of trade books.

How it is used?

Today, almost every edition has its own ISBN number. Code books is installed on the following editions:

• All kinds of brochures, or printed books;
• The publication in which used mixed media;
• Books on CD or tape (audio books);
• Specialized microcomputer SOFTWARE;
• Electronic books
• The Braille edition;
• Publication saved electronically stored;
• Maps.

It is Worth noting the fact that this list is incomplete, and in fact the format of the ISBN today is actively used for the registration of many different books. The print edition is disposable, including all kinds of diaries, calendars, advertising materials and other similar products can not use the record format. This also applies to collections of reproductions without title page and text, or all kinds of sound.

Structure

Book Search by ISBN is carried out by its individual code, which is compiled from the abbreviations, ISBN, and 10 subsequent numbers. It is worth noting the fact that in those countries where the Latin alphabet is not used, the abbreviation can be used with the use of the local alphabet in addition to the ISBN, which is written in the Latin alphabet.

The Code consists of 10 digits divided into four different groups of different lengths, which quite clearly separated from each other by a space or hyphen, it is worth noting the fact that in practice the optimal is the use of a hyphen. The number of digits that are in the first three parts of the code may be different, the number of digits that identifies a particular group or publisher, is determined approximately calculated by the volume of circulation of a particular publisher or group of publishers. If we are talking about publishers or groups with only a small number of publications, in this case, the ID is very short.

Group ID

Country, region, or language area of the system – most importantly, that includes the first part of the ISBN for e-books. It is worth noting the fact that certain parts of the system often enough to form a language region or a unique regional group. The maximum length of this identifier is 5 characters long.

Each group ID is assigned mandatory international ISBN Agency, which is currently in Berlin.

The ID of the publisher

In the second part of this code you can determine what kind of publishing group released a book. Now there is no need to perform a few extra steps if you want to find the book with ISBN. Using the ID of the publisher in the majority of cases, precisely determine not only the name of the publishing house, but also his address. In that case, if the publisher was not off the numbers that are highlighted, then it can be allocated a dedicated identifier of the publisher, the length of which must not exceed 7 characters.

The Identifier of the publishing house assigned a specific literature directly by the ISBN Agency, which is responsible for management of the system in different countries, regions or language areas.

The Identifier of a publication

The Third part of the code determines what kind of specific publication is referred to in a particular publisher. It should be noted that this identifier may have a maximum length of 6 digits, as well as an ISBN must consist of 10 digits, not filled in are filled with zeros.

Check digit

The check digit is the last paragraph in this code. It should be noted that this figure is calculated as the division of the module 11 with a value of 10-2, while if 10 will be the check digit, then replace it with X. It's important to remember, if you don't know how to get an ISBN for the book.

Thus, any digit of the first nine (including a control), eventually multiplied by a number from 2 to 10, and turned out this end result with added to it a control number must be divided by 11 without remainder.

How are the rooms?

The Number of digits in each part may vary, despite the fact that in the sum there should be no more than nine, because these nine digits, together with the key represents the final code that make up the 10 digits.

The Number of digits in the group ID may change depending on the number of publications is present in this group. Thus, in those groups in which there are fewer printed materials, numbers are used from one or two digits, while the edition with large print editions will be given numbers with three digits or more.
