structure
Search Books by ISBN carried out by its unique code, which is made up of the abbreviation of the ISBN, as well as the 10 subsequent numbers.It should be noted that in those countries where the Latin alphabet is not used, an abbreviation may be used with the use of local language in addition to the ISBN, which is written in Latin.
code consisting of 10 digits, divided into four different groups of different lengths, which are quite clearly separated from each other by a space or a hyphen, it is worth noting that, in practice, it is optimal to use a hyphen.The number of digits that are in the first three parts of the code may be different, with the number of digits that identify a specific group, or publishing, about calculate the amount determined by circulations certain publishers or groups of publishers.If we are talking about publishing or groups with only a small number of publications, in this case, the identifier is extremely short.
Group ID
Country, region, or language area system - is the most important thing, that includes the first part of the ISBN for electronic books.It is worth noting the fact that certain portions of the system quite often form language areas or unique regional group.The maximum possible length of the ID is 5 characters.
Each identifier is assigned to a group necessarily using international agency ISBN, which is currently located in Berlin.
ID publishers
In the second part of the code, you can determine which of the publishing group has issued a specific book.There is no need to perform a variety of additional steps, if you want to find a book with ISBN.With the help of a publisher in the overwhelming majority of cases accurately determined not only by the name of the publisher, but also his address.In the event that the publisher had not been off the numbers that are allocated for it, then it can be allocated a dedicated publisher prefix, the length of which must not exceed 7 characters.
identifier assigned to a specific publishing literature directly by the Agency ISBN, which is responsible for the management of the system in different countries, regions or linguistic areas.
ID publication
third part of the code define which particular edition in question in a particular publisher.It should be noted that the ID can not be longer than 6 digits, as well as the ISBN into mandatory shall consist of not less than 10 digits, not filled with zeros.
check digit
check digit is the last point in this code.It is worth noting that this figure is calculated as the modulus 11 with weights 10-2, while if 10 would be the check digit, in this case, it is replaced with H. It is important to remember, if you do not know how to obtain an ISBN for books.
Thus, any number of the first nine (including controls) in the end multiplied by the number of 2 to 10, and received in the end result with the addition thereto the control amount to be divided by 11 without remainder.
How are the rooms?
number of digits in each part can be changed, despite the fact that the amount should be no more than nine, because the nine digits, together with the control represent the final code is made up of 10 digits.
number of digits in the group can vary depending on how many publications in this group is present.Thus, those groups in which the printed products are fewer use numbers from one or two digits, while Publishing large prepared with printed numbers, having three or more digits.
To ensure ease of reading, as well as make it easier to find a book by ISBN, all the parts of the code are separated by hyphens or spaces, and the use of hyphens in the programming phase can significantly reduce the amount of work associated with the introduction of data.
