I. Structure of China Standard Book Number
The structure of China Standard Book Number (ISBN) consists of an international standard book number (1SBN) and a book classification and classification number. The first part of China Standard Book Number (ISBN) is the main part of this numbering system and can be used independently. It consists of 10 digits, separated by a hyphen "one", and is divided into four parts, which respectively represent the group number, publisher number, book number and parity bit. The lengths of the other three segments are variable, except that the parity bit is fixed at one bit, but the sum of the digits of these three segments must be nine bits, and a parity bit is added, so that the digits of the serial number length 1SBN are always equal to 10. When the parity bit is 10, it is represented by the capital letter "X", and when the parity bit is 1 1, it is represented by "O".
(a) the structure of the international standard book number:
1, group number. This paragraph represents the country of the publisher. Geographical area. The number of a language or other grouping feature. The group number is set and assigned by the International 1sBN Center, and the number of digits assigned to China by the International Book Number Center is "7", which can publish 1 100 million books.
2. Publisher number. This paragraph represents the number of a publisher (publishing house, publishing company, exclusive distributor, etc.). ) belongs to the group area. The publication number is set and assigned by the 1SBN center of the country or region to which it belongs, and the length can be 1 ~ 7 digits. China's publication number is assigned by China 1SBN Center, which is divided into five grades with a length of 2-6 digits. The first two digits of ISBN, namely group number and publisher number, are collectively called "publisher prefix", which is the standard code of the only publisher in the world.
3. Book serial number. This paragraph indicates the serial number of a specific publication published by a specific publisher. Every book has a book number, which is assigned by the publishing house itself. Generally, the serial numbers can be numbered according to the order of publication time. The number of digits of the book serial number is constant, and its number is 9 MINUS the number of digits of the publisher prefix.
4. Check the position. This is the last digit of 1SBN, which is used to check the errors in the transcription of 1SBN. (two) the structure of the book classification number:
The second part of the Chinese Standard Book Number (ISBN), that is, the book classification number, is arranged behind (or below) the international standard book number 1SBN, separated by diagonal lines (or horizontal lines). Compared with the national ISBN used in China in the past, the ISBN system lacks book classification marks. In view of the fact that a considerable part of China's publishing information industry is still manually classified, shelved, catalogued and built cards, it is very necessary to print classification marks on books.
1. The book classification number is compiled by the publishing house according to the subject category of books and referring to the basic categories of Chinese Library Classification. Among them, industrial technology books are given according to the second category, so the code of this section is 1 ~ 2 Chinese phonetic alphabet. The classification number is not input into the computer, and is used for book classification, shelving, cataloging and card building, which creates favorable conditions for book classification statistics and book sales and display in bookstores.
2. The serial number is the serial number of similar books published by the same publishing house, which is given by the publishing house itself, and its maximum number shall not exceed the book number in the third paragraph of ISBN number. In addition, some books add specific words after the Chinese standard book number, such as publications in minority languages, and add the words "people's language"; Less reading materials, plus the word "er"; Textbooks, add the word "class" and so on. Example of the structure of Chinese standard book number: publisher prefix group number, publisher number, serial number, parity bit, book classification number, species number,1sbn7-307-00196-9/g52.
Second, the scope of application of China Standard Book Number
China Standard Book Number is applicable to the following publications:
Officially published books and brochures;
(2) Microform publications;
(3) Braille publications;
(four) mixed media publications (audio-visual publications)
(5) machine-readable magnetic tape for producing readable printed copies;
(six) other similar media publications, including teaching films and slides;
(7) Microcomputer software;

Four categories of publications not included in China Standard Book Number:

(three) technical standard documents at all levels (single page);
(four) publications without cover, such as loose-leaf selections.
The above publications can continue to use the national uniform book number, but the publisher number in the uniform book number should be changed to the publisher number in the Chinese standard book number.
ISBN example:
ISBN 962-2 15-00 1-2 ISBN 9622 1500 12
ISBN calculation method multiplies the first nine digits by 10, 9, 8, 7, 6, 5, 4, 3, 2 in turn, and adds the sum to a number in the range of 0 to 10, so that it can be divisible by1. The number added is the audit number. When the audit number is 10, use "x" instead.
National language publishing house title audit digital identification code version code:
9622 1500 1? —x 1098765432_ (respectively multiplied by 10, 9, 8, 7, 6, 5, 4, 3, 2), 90+54+16+14+6+20. So the audit number is "2" and the valid ISBN is: 962-2 15-00 1-2.

Brief introduction of international standard periodical number ISSN
International standard serial number (ISSN) is given to each publication applying for registration by -ISD International Center, an international serial data system in Paris, France, according to the provisions of ISO-3297 formulated by ISO 1975. ISSN has identification function and is uniform internationally.
"Periodical" is a series of periodicals published continuously in a specified period or irregularly. They are usually published under a certain title, and the number of volumes and issues is expressed by "year, month, year" or numbers. Most of the periodicals, magazines, series and annual periodicals in the market belong to the numbering and coding range of international standard periodical numbers. When each periodical is registered, it will get a permanent and unique ISSN, and each ISSN only corresponds to a title; A periodical name has only one serial number. Therefore, when the name of a periodical changes, you must apply for another serial number. If the journal stops publishing, the deleted ISSN will not be used by other journals. Therefore, when distributing ISSN, the International Journal Data System Center must compile a KeyTitle that is different from other journal titles.
